Abstract: A vehicle control system, a vehicle control method, a vehicle controller, and a vehicle relate to the field of vehicle technologies. The system includes: a central controller (10) and a plurality of vehicle components. The plurality of vehicle components belong to a plurality of different functional domains, and a vehicle component in each of the functional domains is directly connected to the central controller (10). A power domain (21) of the plurality of different functional domains includes a motor controller and a plurality of drive motors that are arranged in a one-to-one correspondence with wheels and that independently drive the wheels, and the central controller (10) is configured to send torque allocation information of the drive motors to the motor controller according to a vehicle driving scenario.

Abstract: A vehicle control system and method, and a vehicle relate to the field of vehicle technologies. The system includes: a central controller (10) and a plurality of vehicle components. The plurality of vehicle components belong to a plurality of different functional domains. At least one vehicle component in a first functional domain (21) of the plurality of different functional domains and another vehicle component in the first functional domain (21) are connected to each other through a first network, and are directly connected to the central controller (10). At least one vehicle component in a second functional domain (22) of the plurality of different functional domains and another vehicle component in the second functional domain (22) are connected to each other through a second network, and are directly connected to the central controller (10). At least one vehicle component in the first functional domain (21) is connected to at least one vehicle component in the second functional domain (22) through a third network. The central controller (10) is configured to send control information to at least one vehicle component.

Abstract: The present disclosure relates to a control method for a hybrid vehicle (1000), and a vehicle controller (2000). The vehicle includes an engine (10), a driving motor (20), an electric generator (30) and a power battery (40). The engine is configured to selectively output power to a wheel end. The driving motor is configured to output power to the wheel end. The electric generator is connected to the engine, and driven by the engine to generate electricity. The power battery is configured to supply electricity to the driving motor. The control method includes: acquiring a traveling parameter of the hybrid vehicle; controlling the engine, the driving motor and the electric generator according to the traveling parameter, to enable the engine to operate in an economic zone by charging and discharging control of the power battery; and comparing the equivalent fuel consumptions when the hybrid vehicle is in a series mode, a parallel mode, and an EV mode, to select an operation mode of minimum equivalent fuel consumption as a current operation mode of the hybrid vehicle.
