Abstract: PROBLEM TO BE SOLVED: To provide a holding device for a vehicle braking force and a method therefor which can assist the correction of the deflection of the vehicle when the vehicle is deflected with an unexpected movement of the vehicle with each wheel locked from hill-hold control.
SOLUTION: When a vehicle body acceleration DVS detected during the execution of the hill hold control is "0 (zero)" or more, and a yaw rate YR of the vehicle is not less than a threshold value KYR, a CPU determines that the vehicle is deflected. The CPU reduces the braking force from each wheel cylinder given to each wheel. Each wheel is unlocked, and the deflection of the vehicle due to the steering of the front wheel of a steered wheel can be corrected.

Abstract: PURPOSE:To shorten braking distance by detecting acceleration slip according to the outputs of a braking operation detecting means and a wheel speed detecting means, and correcting braking forces to be applied to driving wheels so that they are increased when braking operation is carried out during detection of acceleration slip. CONSTITUTION:A braking force control means M5 is provided which drives a fluid pressure control device M2 when the output signals of a vehicle acceleration detecting means M3 and wheel speed detecting means M4 for driving wheels RR, RL are input thereto, thereby controlling brake fluid pressure to be supplied to wheel cylinders 53, 54 located on the side of the driving wheels. An acceleration slip detecting means M7 is provided which outputs an acceleration slip signal when such a state that the rate of lowering of the wheel speed exceeds a predetermined value is continued while braking operation of a braking operation member M0 is not detected by a braking operation detecting means M6. When braking operation is detected and the state in which acceleration slip is detected is continued, then the braking force control means M5 is controlled by a braking force correcting means M8 so as to increase braking forces to be applied to the driving wheels.

Abstract: PURPOSE:To prevent the overshoot of the temp. of a detection part, in an oxygen sensor detecting the concn. of oxygen in the exhaust gas of a vehicle, by deciding whether the control of the supply of a current to the heater of a sensor is performed corresponding to the state of the vehicle to suppress power for a predetermined period when the control is decided to be performed. CONSTITUTION:The current supply condition decision means M1 of a heater controller HC decides whether the supply of a current to the heater HT of an oxygen sensor DS is performed corresponding to the state of a vehicle for a definite time after starting, for example, when a start motor is operated in order to protect a battery or atmospheric temp. is extremely low. When it is decided to perform the control of the supply of a current, the power suppressing means of a motor power control means M2 is controlled by the means M1 and the supply of a current to the heater HT is suppressed for the first predetermined period of current supply. By this method, it is prevented that the temp. of the detection part of the sensor overshoots.

In an ECU for controlling the actuator 12, the minimum value and maximum value of wheel speed after the brake fluid pressure is reduced are detected according to wheel speeds and the recovery acceleration of the wheel speed from the minimum value to maximum value is calculated. When the recovery acceleration is less than a set value, vehicle acceleration detected by an acceleration detecting means 21 is corrected to a smaller one and estimated vehicle speed and the like are calculated according to the vehicle acceleration after correction.
