When the start of movement of the vehicle is detected during an operation of returning the brake pedal (t4) and an operation of re-depressing the brake pedal is detected (t5) in this state (specifically, while the vehicle is in a stopped state, the hydraulic pump is in a stopped state, and the brake pedal is being operated), the driving of the hydraulic pump is started (t5).

Abstract: A control apparatus controls acceleration of a vehicle provided with a motive power generation apparatus and brake apparatuses. For the control, the control apparatus comprises calculation and actuating blocks. The calculation block calculates torque to be requested, based on a difference between an actual value of the acceleration and a target value thereof and a gain for feedback controlling the actual value of the acceleration to the target value thereof. The gain is differentiated in value between in a first case in which the brake apparatuses are used for the feedback control and a second case in which the brake apparatuses are not used for the feedback control. The actuating block actuates the motive power generation apparatus and the brake apparatuses based on the calculated torque. The value of the gain in the first case is made larger than the value of the gain in the second case.

Abstract: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.

Specifically, the vehicle speed control device calculates a drive force including a feedforward component corresponding to the set speed and a travel resistance against the travel of the vehicle, and a feedback component corresponding to a deviation of the set speed from the actual speed of the vehicle as a desired axle torque. The vehicle speed control device interrupts the cruise control when a requested drive axle torque requested by an accelerator operation during the cruise control exceeds the desired axle torque, and restarts the cruise control when the requested drive axle torque becomes lower than the desired axle torque.

The motive power generation apparatus has an output shaft producing a rotation force in response to a command to be requested.

The calculated feedback manipulated variable is used as the command. When the staged transmission apparatus is in the switchover control of the gear ratios, the manipulated variable is is limited from being calculated (for example, stopped from being calculated).

Abstract: An estimated gradient value of a road is calculated based on a vehicle acceleration “A” and a time varying portion “A?” of a wheel speed. In a case that an acceleration corresponding value “Ggrad0” for the estimated gradient value is not regarded as indicating an exact figure, due to influences of disturbances, the acceleration corresponding value “Ggrad0” is corrected by a limiting value for rate-of-change with regard to the road gradient depending on respective vehicle speed, and by a limiting value for the road gradient. As a result, the acceleration corresponding value “Ggrad” for the estimated gradient value can be more exactly obtained.

Abstract: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.
