Abstract:
A running control apparatus for a vehicle includes a required driving output deciding unit that decides a required driving force of a driving system of the vehicle on the basis of an integrated value of a difference between a target vehicle speed and an actual vehicle speed, a driving control unit that controls the actuation of the driving system on the basis of the required driving force, and a determination unit that determines whether or not the required driving force is unrealizable in the control of the driving system due to the intervention of additional control. The required driving output deciding unit imposes a limit on an increase or a decrease in the required driving force when the determination unit determines that the required driving force is unrealizable in the control of the driving system.
Abstract:
A road slope determining apparatus for a vehicle includes a slope measuring device that measures a slope of a road on which the vehicle is traveling; a distance measuring device that measures a distance traveled by the vehicle; and a determining apparatus that determines, based on the measured slope and the measured distance traveled, whether the vehicle is traveling on a gradient in which the slope is continuous or on a rough road in which the slope is discontinuous. This road slope determining apparatus is able to appropriately determine whether the road has a slope when the vehicle is traveling at slow speeds such as when running off-road, for example.
Abstract:
A vehicle controller includes an obstacle-determining portion and a driving torque reducing portion. The obstacle-determining portion determines whether the vehicle is climbing up an obstacle,more specifically, whether the vehicle starts climbing up the obstacle. Them, the driving torque reducing portion performs a driving torque reduction control when it is determined that the vehicle is climbing up onto the obstacle.
Abstract:
A vehicle brake control system includes an electric fluid pump that, upon energization thereof, pumps brake fluid from a reservoir to a brake circuit at a position upstream of a pressure control valve, an inlet circuit connecting the inlet opening of the pump to a master cylinder, an inside gate valve installed in the inlet circuit, and a control unit that controls the pressure control valve, the inlet gate valve and the electric fluid pump and carries out a predetermined brake control to adjust the hydraulic pressure of the wheel cylinder by operating the pressure control valve. The control unit is configured to carry out a flow back control after completion of the predetermined brake control. The flow back control is a control wherein the inside gate valve is kept open having the electric fluid pump kept de-energized.

A vehicle control device for controlling the driving force and braking force that is applies to a vehicle to maintain a target wheel speed includes: a plurality of determination parts each of which determines the wheel speed of a corresponding one of a plurality of wheels of the vehicle; a calculation part that calculates the wheel speed validity threshold for each wheel based on the determined wheel speeds; a decision part that decides whether the wheel speed validity threshold calculated for each wheel is below a specific threshold speed; a setting part that resets the target wheel speed depending on the result of the decision by the decision part; and an estimation part that estimates the vehicle speed based on the determined wheel speeds.
Abstract:
A vehicle drive control device includes a wheel speed detecting means for detecting a rotational speed of a plurality of wheels of a vehicle, a vehicle speed calculating means for calculating a vehicle speed on the basis of the rotational speed of the plurality of wheels detected by the wheel speed detecting means, and an automatic drive controlling means for performing an automatic drive control for controlling the vehicle speed to be a predetermined target speed by controlling a driving force generating means and a vehicle speed reducing means for the vehicle. The automatic drive controlling means further performs a driving force reducing control for reducing a driving force of the vehicle to be generated by the driving force generating means when the rotational speed of at least one of the plurality of wheels detected by the wheel speed detecting means exceeds a predetermined value.
Abstract:
A vehicle cruise control apparatus includes a vehicle speed adjusting device that adjusts a vehicle speed to a set target vehicle speed, a brake operation detecting device that detects brake operation performed by a driver, and a first controller that controls the vehicle speed adjusting device based on a target driving force that maintains a vehicle in a stopped condition, when the brake operation performed by the driver is detected.
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.
