摘要： The vehicle control apparatus is provided with a vehicle body speed deriving portion that derives a vehicle body speed of a vehicle, a wheel speed difference deriving portion that derives a wheel speed difference which is a deviation between the maximum wheel speed and the minimum wheel speed of the wheels of the vehicle, a request drive amount deriving portion that derives a request drive amount for the drive source of the vehicle, a torque suppressing device that suppresses torque of a driving wheel, a traction control portion that controls the torque suppressing device and suppresses an acceleration slip of the driving wheel based on the wheel speed difference or a combination of the wheel speed difference and at least one of the vehicle body speed and the request drive amount.

摘要： According to one embodiment, for example, when it is determined that a certain condition has been satisfied while first antilock control is being executed, a controller of a brake control apparatus executes second antilock control by opening and closing a solenoid valve with a motor stopped so that brake fluid of the wheel cylinder is caused to flow into a reservoir, the second antilock control including a second pressure reduction mode, the second pressure reduction mode reducing a pressure of a wheel cylinder while substantially equilibrating the pressure of the wheel cylinder and a pressure of the reservoir at a certain pressure or larger, the certain pressure being larger than zero.

摘要： A braking control apparatus performs right and left wheel independent control to approach a slip rate of a rear-right wheel and a rear-left wheel to a target slip rate as an average of slip rates of a front-right wheel and a front-left wheel. In a high-speed range, right and left wheel independent control is started when a deceleration is equal to or larger than a start value that is smaller than a start value used in a low-speed range. In right and left wheel independent control started in the high-speed range, when there is a demand to increase braking pressures of both the rear-right wheel and the rear-left wheel, the braking pressure of the rear wheel located on the outside during the occurrence of deflection of the vehicle resulting from braking is increased, and the braking pressure of the rear wheel located on the inside is prohibited from increasing.

摘要： A braking force control apparatus is provided which has an upstream braking actuator for generating an upstream pressure common to four wheels, a downstream braking actuator individually controlling braking pressure supplied to braking force generating devices of the wheels using the upstream pressure, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to the braking force generating devices, but a braking pressure of any one of the wheels cannot be normally controlled, the control unit selects a control mode on the pressure increasing side out of the front wheel control modes, selects a control mode on the pressure increasing side out of the rear wheel control modes, selects a control mode on the pressure decreasing side out of the two selected control modes as a prescribed control mode, and controls the upstream pressure in the prescribed control mode.
