Abstract: A method is disclosed for controlling a change in the direction of travel of a working vehicle between forward travel and rearward travel or vice versa. The working vehicle has an electronically controllable hydrostatic travel drive, a power-operated brake system with at least one electronically controllable brake circuit, and an electronic brake-control unit for controlling the travel drive and the brake circuit. While the vehicle is traveling in a first direction, a change in the direction of travel is triggered by a switchover of the hydrostatic travel drive by means of an assigned manual operating element. To reduce the mechanical loading, the deceleration of the working vehicle can be assisted by automatically actuating the brakes of the electronically controllable brake circuit, where these brakes are actuated by being triggered by the switchover of the operating element and are released by the time the vehicle comes to a standstill.

Abstract: To inhibit clutch engagement during an engine restart from affecting cooperative regenerative braking control and switching of braking in a hybrid vehicle having a P2 module onboard, a control system for the hybrid vehicle includes an engine, a motor, a K0 clutch, drive shafts, a hydraulic friction brake system, and a controller capable of performing cooperative regenerative braking control. When start of the engine is requested during the cooperative regenerative braking control, the controller performs a first process of transitioning to braking only by the frictional brake system, a second process of raising an engine revolution speed while engagement of the K0 clutch is initiated after completion of transitioning to the braking, and a third process of controlling the engine to resume operating at a timing after the engine revolution speed increases to match a motor revolution speed after the engagement of the K0 clutch is initiated.

Abstract: A vehicle control system includes a target drive force calculation unit, an arithmetic unit, a stop holding unit, a power-running-generative drive force calculation unit, and a traveling mode selection unit. The arithmetic unit calculates required drive force and required brake force based on target drive force calculated by the target drive force calculation unit. The arithmetic unit calculates the required drive force by setting the required brake force to stop hold brake force or greater if an engine traveling mode is selected at an immediately preceding timing by the traveling mode selection unit. The arithmetic unit calculates the required brake force by setting the required drive force to less than or equal to power-running-generative drive force calculated by the power-running-generative drive force calculation unit if an electric vehicle traveling mode is selected at the immediately preceding timing by the traveling mode selection unit.

Abstract: A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes, during deceleration of an automobile, a gear-shifting control of changing a shift stage of the automatic transmission by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft and a regeneration control of performing regeneration by at least one of distributing a braking force by the friction brake system and imparting a regenerative braking torque to rear wheels by causing the motor to perform a regeneration operation. The controller executes a first coordinated gear-shifting control of reducing hydraulic pressure in the friction brake system and, at the same time, changing the shift stage while continuing the regeneration operation during brake regeneration and executes a second coordinated gear-shifting control of changing the shift stage after increasing an input torque during non-brake regeneration.

Abstract: A technique is provided in which detection of an impending collision results in the vehicle's control system taking steps to minimize damage to the passenger cabin, thereby increasing passenger safety. In particular, once an object is detected in the vehicle's pathway, the on-board controller determines whether or not a collision with the object (e.g., an on-coming car or a stationary object) is imminent. Once the system determines that a collision is imminent, the controller (i) deactivates the car's anti-lock braking system, (ii) locks-up the wheels, and (iii) rotates the front wheels to minimize intrusion of the wheels into the passenger cabin. The system may be configured to tailor the response to an imminent collision based on (i) vehicle speed, and (ii) probable impact area.
