摘要： A vehicle control system and a vehicle control device can switch control of a supporting device for support a drive of a vehicle between an ordinary travel in which the vehicle travels in a state that a power source for causing the vehicle to travel is operated and an inertia travel in which the vehicle travels in a state that an operation of the power source is stopped. Accordingly, since the vehicle control system and the vehicle control device switch the control of the supporting device between the ordinary travel and the inertia travel, the vehicle control system and the vehicle control device achieve an effect that the vehicle can be caused to appropriately travel by inertia.

摘要： A variator torque control system adjusts a variator output so that the actual output torque of the variator closely matches an expected output torque. In an example, pressure values of an existing torque control map are supplemented in real time with calculated pressure supplement values based on the current operation of the variator. The pressure supplement value for each mapped pressure value may be derived based on a prior application of the same or another map value.

摘要： A power transmitting apparatus for a vehicle mounted with a torque converter and an idle-stop mechanism can be configured to improve fuel economy without cancelling a fuel-cut-ff during vehicle speed reduction and to reduce the manufacturing cost by eliminating an electrically-driven oil pump. A power transmitting apparatus can comprise a torque converter, a clutch mechanism, an oil pump, a continuously variable transmission, a clutch control device, an engine control device, and a flow control device. The flow control device can be configured to limit or prevent the supply of oil to the torque converter by the oil pump and to prioritize the supply of oil to the clutch mechanism and the continuously variable transmission when the vehicle speed is reduced below a predetermined value with fuel being cut off by the engine control device during vehicle speed reduction.

摘要： A hydrostatically driven vehicle has an engine operating a variable displacement propel pump, a displacement of which can vary based on an angle of a rotating swashplate, such that a fluid flow impelled by the pump transfers power to at least one propel motor rotating a wheel of the vehicle. An electronic controller of the vehicle senses an operating parameter of the system, for example, the angle of the rotating swashplate or the direction and speed of rotation of the propel motor with a sensor to yield an actual signal, and relays the actual signal to an electronic controller. The controller determines a desired angle for the rotating swashplate based on the control signal, and compares it to the actual signal from the sensor. Motion of the vehicle is stalled when the angle signal differs from the desired angle by a predetermined extent and for a predetermined period.

摘要： A cruise control system for a utility vehicle, which is speed-controlled by a hydrostatic transmission, includes a controller having an input for receiving a selectable set speed signal, and an output for sending a speed control signal to at least one proportional valve of a hydrostatic transmission servo control system. The vehicle ground speed is continuously monitored by a speed sensor operatively associated with a rotating gear in the vehicle drive train that rotates in proportion to vehicle ground speed, to create a ground speed signal. The selectable set speed signal can be input to controller memory by driving the vehicle at a desired ground speed and then activating a speed set switch. The speed control algorithm of the controller thereafter compares the set speed to the ground speed signal from the speed sensor and corrects the control signal to the proportional valve to correct hydrostatic transmission speed output.
