Abstract:
A dual function handlebar mounted actuator has means for operating a first function and means for operating a second function with the first and second function operating means being arranged for activation by movement of a hand operated lever arrangement. The first and second functions operating means are linked so that a combined first and second function can be activated and the first and second functions are a clutch and a brake function. The actuator has a lever movable between a first and a second position, and a master cylinder having a piston with the lever moving towards the second position to drive a piston from its initial position thereby increasing pressure in the master cylinder. By releasing the lever the pressure within the master cylinder is arranged to return the piston towards its initial position and the piston being returned fully to the initial position upon movement of the lever to the first position.
Abstract:
A boat propulsion system interposed between a prime mover and a propeller shaft comprises a hydro-mechanical transmission including a hydrostatic transmission part and a gear transmission part. The hydrostatic transmission part includes a variable displacement hydraulic pump having a movable swash plate and a hydraulic motor fluidly connected to the hydraulic pump. The hydraulic pump is driven by the output rotary force of the prime mover. The gear transmission part is drivingly interposed between the hydrostatic transmission part and the propeller shaft so that the gear transmission part is driven by the input rotary force of the hydraulic pump with the assistance of the output rotary force of the hydraulic motor. A hydraulic clutch system may be interposed between the gear transmission part of the hydro-mechanical transmission and the propeller shaft so as to select one of opposite output rotary directions of the propeller shaft.
Abstract:
A watercraft has an engine that is controlled to provide a comfortable and natural operational feeling during an off-throttle steering environment. The engine is controlled by detecting engine speed, using the detected engine speed to establish an accurate watercraft speed, and detecting an operator steering torque and operator engine torque request. An operational characteristic of the engine is adjusted to increase the engine output by a predetermined amount after a predetermined steering torque is measured and the watercraft is determined to be in a predetermined deceleration phase. The operational characteristic can be an increase in airflow to the engine.
Abstract:
An electrically controlled transmission system for a marine vessel that is adapted to avoid vibration to the vessel during a shifting process of the transmission system. The transmission system includes a marine vessel having an inboard motor and an outboard propulsion drive. The motor is coupled to the propulsion drive by the transmission assembly which is at least partially located within a portion of the outboard propulsion drive and is adapted to provide substantially vibration-free shifting of the transmission assembly. The transmission assembly has a drive shaft selectively engageable with at least a forward and reverse gear of the propulsion drive for establishing forward and reverse configurations of the transmission assembly, respectively. The transmission assembly is also electrically and remotely controlled from a distance therefrom between the forward and reverse configurations utilizing electrically actuatable solenoids. These solenoids are located proximate to the transmission assembly and are used for establishing the forward and reverse configurations of the transmission assembly thereby enabling the substantially vibration-free shifting in the transmission assembly. The actuable solenoids are interconnected with a hydraulic system for affecting the forward an reverse configurations. A first remote control is located away from the transmission assembly and is communicatively connected with the electrically actuatable solenoids for configuring the transmission assembly between the forward and reverse configurations, and a neutral configuration.
Abstract:
A control system controls a hybrid vehicle having an engine for rotating a drive axle, an electric motor for assisting the engine in rotating the drive axle with electric energy and converting kinetic energy of the drive axle into electric energy, and an electric energy storage unit for supplying electric energy to the electric motor and storing electric energy outputted by the electric motor. The control system has a deceleration demand sensor for detecting a deceleration demand for the hybrid vehicle, a braking sensor for detecting whether the hybrid vehicle is braked or not, and a decelerating regenerative control unit for causing the electric motor to regenerate electric energy when the deceleration demand sensor detects the deceleration demand. The decelerating regenerative control unit increases an amount of electric energy regenerated by the electric motor, by a greater quantity when the hybrid vehicle is braked as detected by the braking sensor than when the hybrid vehicle is not braked as detected by the braking sensor, while the deceleration demand sensor is detecting the deceleration demand.
Abstract:
A control handle for the tiller of an outboard motor that embodies a twist-grip throttle control, a pivotally supported transmission control and a trim switch, all juxtaposed to each other but oriented in such a way so that actuation of one will not affect accidental actuation of any other control. The trim control is disposed in a projection on the lower side of the outer housing of the control handle and is disposed inwardly from the sides thereof and is protected by a flange.

A method and system, for use with a vehicle including a pair of front wheels, a pair of rear wheels, and an anti-lock brake system (ABS), for detecting when the vehicle is executing a turning maneuver. The system includes means for performing the method steps of determining a speed difference between one pair of the vehicle wheels, determining the deceleration of each of the one pair of vehicle wheels, comparing the speed difference to a turning detection threshold, comparing the decelerations to a deceleration threshold, and detecting a turning maneuver based on those comparisons.

A method/system for controlling an automated transmission is provided wherein upon assembly of a vehicle, the intercept (A) and slope (B) values defining the presumed linear relationship between engine deceleration rate and engine accessory torque (dES/dt rate=A+(B * T.sub.ACCES)) and/or the value of engine rotational moment-of-inertia (I) for that particular vehicle are determined and memorized. Thereafter, the transmission is controlled as a function of these determined values.

Abstract:
A control system for engaging, disengaging and re-engaging a differential locking mechanism in an agricultural vehicle includes a control circuit configured to receive signals representative of vehicle operating parameters and to generate control signals corresponding to the desired state (i.e. engaged or disengaged) of a differential locking mechanism for limiting relative velocity between two driven wheels. Sensors are associated with the rear wheels, rear service brakes, implement positioning circuit, the vehicle body and the front axle to provide parameter signals related to wheel speed, braking, implement position and vehicle speed. Control logic executed by the control circuit in a continuously cycled routine determines the desired state of the differential locking mechanism based upon the operating parameters. The control circuit applies an appropriate control signal to the differential locking mechanism causing engagement or disengagement in accordance with the desired state.
Abstract:
In an automatic transmission control system provided for an internal combustion engine having an automatic transmission system equipped with a traction control system in which a throttle valve is adjusted towards a closed state from a throttle position corresponding to an operation of an accelerator pedal when wheel slippage occurs, a detection unit detects a degree of operation of the accelerator pedal. A shift point changing unit changes a shift point so that gear shifting occurs on the basis of the degree of operation of the accelerator pedal in a normal state and gear shifting occurs at an engine speed lower than a predetermined engine speed at which gear shifting normally occurs when the degree of operation of the accelerator pedal is equal to or greater than a predetermined value.
