Braking controller for vehicle

Abstract: PROBLEM TO BE SOLVED: To prevent the sharp change of the deceleration of a vehicle when a shift is made between a cooperative braking mode for friction braking and reclaiming braking and a single braking mode for friction braking. SOLUTION: A target reclaiming braking force and a target friction braking force are calculated on the basis of the normal deceleration rate Gbt of the vehicle based on the amount of braking operation by a driver so as to make a reclaiming braking force as large as possible. In a normal traveling, the braking force of the vehicle is controlled under the cooperative mode for the reclaiming braking and friction braking (S100 to 210). At the first or a prescribed time of braking control, the braking force of respective wheels is controlled under the single braking mode using the friction braking, where a compensation factor Kp is calculated as the ratio between the actual deceleration rate Gbx and the normal deceleration rate Gbt of the vehicle at this time (S90, S220 to 280), then the target friction braking force is compensated to be increased to Kp times (S190). In this manner, the change of the total braking force of the vehicle is prevented when the braking mode is shifted between the cooperative braking mode and the single braking mode, so that sharp change of the deceleration of the vehicle is prevented (S110 to 210).

ABS braking system for vehicle

Abstract: The ABS control system is improved using fuzzy logic which takes into account the slewing forces on the vehicle and any instability caused by braking. The braking program is modified to provide a balanced braking control by monitoring the changes in the slewing forces etc. The system monitors the changes in wheel speed, steering setting, speed etc. The system is extended by including rear wheel steering in which the steering setting of the rear wheels is compared with the steering setting of the front wheels and the dynamics of the vehicle. Fuzzy logic is also applied to the control of the rear wheel steering.

Control device and method for signaling a braking process at a trailer vehicle

Abstract: The invention relates to a control device and method for signaling a braking process at a trailer vehicle. The control device determines at least one braking value that is assigned to the braking process, and actuates at least one brake light as a function of the braking value. The braking process is signaled differently for different braking values determined by the control device during a braking process. As a result, traffic following the trailer vehicle and/or an emergency braking situation can be signaled and, therefore, safety in road traffic can be increased.

Brake control device and control method

Abstract: A hybrid vehicle includes a braking device configured to apply a frictional braking torque to a vehicle wheel in response to movement of an input member of a brake pedal, an electric motor configured to apply a regenerative braking torque to the vehicle wheel, and a control unit. During braking, the control unit is configured to determine a limit value of the regenerative braking torque that can be generated in accordance with an operating condition of the charging device or the electric motor, and reduce a ratio of the regenerative braking torque to the frictional braking torque before the regenerative braking torque reaches the limit value.

Study on Methods of Regenerative Braking Energy of Automobile

Abstract: The principle of the regenerative braking energy of automobile is introduced. Three types of the regenerative braking system, i.e., energy accumulator of the flywheel, hydraulic pressure and electrochemistry, are discussed. By comparing three types of energy storage methods, a new regenerative braking system is proposed. This type of regenerative braking system has some advantages, such as reclaiming braking energy of automobile, generating electricity, starting engine, and assisting acceleration power of automobile. About 10% -30% fuel can be saved when driving under city conditions.
