The brake control device puts automatic braking into operation by generating the oil pressure in the vehicle stabilizing device when an impact is detected by a collision detection sensor, and in a case where an abnormality of the vehicle has been detected during operation of the automatic braking, the brake control device controls the vehicle stabilizing device to stop operation of the automatic braking in accordance with influence on operation of the automatic braking.

Abstract: A vehicle brake system includes a collision determination unit that determines whether collision of the vehicle occurs or not; and a second braking control unit that, when the collision of the vehicle is determined as occurring, causes at least either of an ESB system and a VSA system to perform emergency braking control of the vehicle, and causes the VSA system to perform ABS braking control based on an ABS brake demand depending on a slip state of each wheel, irrespective of whether a brake pedal is pressed down or not. In a case where the vehicle collides, where the brake operation is performed, and where the ABS braking control is performed, the second braking control unit causes the emergency braking control based on an emergency brake demand to be continued instead of the braking control based on the press-down operation of the brake pedal by a driver.

In a case where the collision of the vehicle occurs, and where the demanded braking force exceeds the braking force threshold, the second braking control unit retreats an operation position of the brake pedal in a press-down direction.

Abstract: The control property of an onboard device is changeable by using an external control unit, and the data from the external control unit is authenticated. An onboard gateway unit is provided with a verification code generator for generating a security key, and an external control unit is provided with an application control unit for generating a security key.
