  • Publication number: 20240001910
    Abstract: A vehicle movement control device generates a target motion vector that falls within a desired controllable range in a motion space, and integrally controls a plurality of actuators to realize a vehicle movement defined by the target motion vector, thereby improving ride comfort and operation feeling. The vehicle movement control device that controls the plurality of actuators in accordance with a travel state, the vehicle movement control device including: a vehicle movement planning unit configured to generate a target motion vector based on input travel state information; an operation amount arbitration unit configured to calculate an operation amount of each actuator based on the target motion vector; and an actuator control unit configured to control each actuator based on the operation amount, in which the vehicle movement planning unit generates the target motion vector within a controllable range in a motion space acquired from the operation amount arbitration unit.

  • Patent number: 9463782
    Abstract: A brake control system which can maintain the behavior of a vehicle stable when wheels slip. A slip amount detector (56), configured to detect an amount of slip at the front and rear wheels, is connected to a second ECU (35). A first ECU (27) has a regenerative slip control unit which executes repeatedly a slip restricting control in which, while the front wheels are being detected as slipping based on a detection value of the slip amount detector during the execution of regenerative braking by a motor-generator (55), the amount of regenerative braking by the motor-generator is reduced by a predetermined amount, and thereafter, the resulting reduced amount of regenerative braking is held for a predetermined period of time. The regenerative slip control unit sets the predetermined reduction amount larger than a predetermined reduction amount by which the amount of regenerative braking is reduced in the slip restricting control.
