Patent number: 9637116Abstract: A vehicle configured to suppress a variation in a deceleration during braking. When a regeneration braking force is generated by a hybrid ECU to brake a hybrid vehicle, and an abnormality occurs to communication between the ECU and a brake ECU, the ECU gradually decreases a magnitude of a target regeneration braking force as the time elapses. On the other hand, the ECU gradually increases a magnitude of a target friction braking force up to a magnitude of a target total braking force as the time elapses. Further, when the vehicle is braked, and power supply to the ECU is shut off to result in an abnormality in the communication between the ECU and the ECU, the ECU finishes the regeneration operation of an electric motor, and the ECU rapidly increases the magnitude of the target friction braking force to the magnitude of the target total braking force.Type: GrantFiled: October 29, 2014Date of Patent: May 2, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuya Miyazaki, Daisuke Nakata
