An automobile brake control method, a device, and an automobile. The method includes performing a real time monitoring for failure on an automobile brake system in real time; obtaining automobile working condition information when the automobile brake system is in a failure state; generating a failure determination result according to the automobile working condition information in the failure state; generating a reverse-dragging brake instruction corresponding to reverse-dragging brake condition and sending it to a motor controller, enabling the motor controller to perform the reverse-dragging brake according to the reverse-dragging brake instruction when determining the automobile working condition information after the failure of the brake system satisfies the reverse-dragging brake condition corresponding to the failure determination result. The method can control the motor to perform reverse-dragging brake when the brake system fails or the performance is reduced to a certain extent, so as to effectively improve the safety of the automobile.

A vehicle running control device that is provided with an accelerating-decelerating operation element with an operation range inclusive of a driving range and a braking range includes the following. An input-output section that receives various information including information on a direction in which the vehicle is currently running, a determining section that determines whether the vehicle is in a switch-back state, and an acceleration-deceleration control section that controls the vehicle running. When a braking-driving request value for an operation of the accelerating-decelerating operation element is in the braking range and the determining section determines that the vehicle is in the switch-back state, the acceleration-deceleration control section keeps the braking-driving force at a braking-driving force that is applied to the vehicle when a shift range switch request is accepted.

The disclosure relates to a method for operating a hydraulic braking system for a motor vehicle with an electrified drive train. The braking system comprises a brake booster. First, a braking request is registered and it is determined that the braking request is to be met by pure recuperative braking. In addition, an input member of the brake booster is shifted in the direction of a pressure generation unit so that it assumes an actuation position corresponding to the braking request. From here, the input member is then shifted back from the actuation position in a direction away from the pressure generation unit for hydraulic pressure relief. A control unit designed to carry out such a method is also disclosed. A braking system comprising such a control unit is also presented.

A braking control apparatus includes a braking force control unit, a first abnormality detecting unit, a regenerative brake stopping unit, and a braking force compensating unit. The braking force control unit is configured to perform a braking force control by causing an engine brake, a regenerative brake, and a friction brake to operate in cooperation with each other. The regenerative brake stopping unit is configured to disconnect the regenerative brake from the braking force control, when an abnormality of the regenerative brake is detected by the first abnormality detecting unit. The braking force compensating unit is configured to perform a braking force compensation that utilizes the friction brake, from the detection of the abnormality of the regenerative brake until the regenerative brake is disconnected from the braking force control, by performing a feedback control on a deceleration rate at a time when the abnormality of the regenerative brake is detected.

To sufficiently exert charging and discharging performance of a cell while reliably protecting the cell, a battery controller determines ΔVlimit which is a limit value for a difference between a CCV and an OCV of a cell module, which is a secondary cell, and determines at least one of an upper limit voltage and a lower limit voltage of the cell module. An allowable current of the cell module is calculated based on the ΔVlimit and at least one of the upper limit voltage and the lower limit voltage determined in this manner.
