Abstract: A system for controlling a vehicle, includes: a central controller and multiple vehicle components. The vehicle components correspond to multiple functional domains, and at least one vehicle component in each of the functional domains is connected to the central controller. The central controller is configured to send first control information to the at least one vehicle component. The functional domains includes a power domain. A vehicle component in the power domain includes a motor controller and multiple drive motors corresponding to wheels and respectively driving the wheels. The first control information includes torque allocation information of each of the drive motors. The central controller is configured to send the torque allocation information to the motor controller according to a vehicle driving scenario.

Abstract: A vehicle control system includes: a central controller and a plurality of vehicle components belonging to a plurality of different functional domains. At least one vehicle component in a first functional domain of the plurality of different functional domains and another vehicle component in the first functional domain are connected to each other through a first network, and are directly connected to the central controller. At least one vehicle component in a second functional domain of the plurality of different functional domains and another vehicle component in the second functional domain are connected to each other through a second network, and are directly connected to the central controller. At least one vehicle component in the first functional domain is connected to at least one vehicle component in the second functional domain through a third network. The central controller can send control information to at least one vehicle component.
