Abstract: In a vehicle travel controlling apparatus including an automatic travel controlling ECU that controls a vehicle in a predetermined travel state by cooperation control of a vehicle driving amount and a vehicle braking amount, the automatic travel controlling ECU is provided with an automatic travel termination controlling unit. The automatic travel termination controlling unit obtains a brake fluid pressure during the cooperation control according to the vehicle driving amount during the cooperation control and a gradient of a road surface on which a vehicle is travelling. When the brake fluid pressure corresponding to a braking operation of a driver is more than the brake fluid pressure during the cooperation control, the automatic travel termination controlling unit terminates the cooperation control to switch operation to a braking operation according to the brake fluid pressure corresponding to the braking operation.

Abstract: A retarding unit in a vehicle is automatically controlled based on conditions including a current setting of the retarding control, downhill grade, speed, current gear, and impending gear change. With the retarder control set in the high position, when the vehicle is operating at a downhill angle greater than the low angle threshold and less than the high angle threshold, and the pending gear is a large step downshift, automatically setting a retarder level to a low retarder level. When the vehicle is operating on level ground and the pending gear is a large step downshift or the current gear is first or second gear, automatically setting the retarder level to off. When the vehicle is operating on flat ground and the deceleration is above a trigger level, automatically setting the retarder level to a low retarder level.

Abstract: A vehicle braking control system includes a vehicle brake associated with a wheel on the vehicle. A pedal activated by an operator of the vehicle controls application of the brake. An electronic control unit determines a grade mode of the vehicle and controls application of the brake independent of the operator activating the pedal while in an automatic braking mode. The electronic control unit sends a control signal to apply the brake in a manner to reduce brake fade while controlling a speed of the vehicle when the electronic control unit is in the automatic braking mode and the vehicle is in a downhill grade mode.

Abstract: An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.
