Electric vehicle controller enterprise and supporting relationship list

First, the vehicle controller definition and main functions

The vehicle controller is the powertrain controller of the electric vehicle. After collecting the accelerator pedal signal, brake pedal signal and other component signals, and making the corresponding judgment, it controls the action of the controller of each component of the lower layer, which can realize the vehicle drive, braking and energy recovery.

The main functions of the vehicle controller are as follows:

Vehicle driving: collect drivers' driving needs and manage vehicle power distribution.

Network management: Monitoring communication network, information scheduling, information summary, gateway.

Auxiliary drive of the instrument.

Fault diagnosis: Diagnose and handle faults of sensors, actuators, and other components of the system, and store fault codes in standard formats. Standard fault code display.

Online configuration and maintenance: through the vehicle standard CAN port, control parameter modification, matching calibration, function configuration, monitoring, debugging ability based on standard interface, etc.

Energy management: Through the coordination and management of the on-board energy consumption system of electric vehicles, to obtain the best energy utilization.

Power distribution: Through the integration of vehicle information, battery and motor information to calculate the motor power distribution, drive and brake energy feedback control of the vehicle, so as to obtain the best driving performance under the permission of the system.

Control and fault diagnosis of vacuum booster pump, electric brake auxiliary control when vacuum pump fails.

Ramp parking assist control.

Control to prevent backsliding at the start of the ramp.

Second, vehicle controller enterprise and supporting relationship

As the core components of electric vehicles, vehicle companies mostly develop and produce vehicle controllers and system designs.
