Abstract

The invention discloses a simulation testing method, apparatus and system for a vehicle control unit. The simulation testing method includes the steps: determining a driving requirement for a current driving scene; according to the driving requirement and the driving operation information for a simulation driver in the current driving scene, generating a vehicle simulation control signal; sending the vehicle simulation control signal to a vehicle control unit to be tested to enable the vehicle control unit to control a simulation vehicle according to the vehicle simulation control signal and output the vehicle operating state information; and judging whether the vehicle operating state information is in accordance with the preset operating state information so as to determine whether the vehicle control unit to be tested can correctly process the current driving scene. The simulation testing method, apparatus and system for a vehicle control unit can verify whether the functional design of the vehicle control unit satisfies the driving requirements in different driving scenes for different types of users so as to verify the integrity of the functions of the vehicle control unit.

Description

technical field [0001] The invention relates to the technical field of vehicle controller testing, in particular to a simulation test method, device and system for a vehicle controller. Background technique [0002] Based on the factors of environment, energy and technological development, new energy vehicles are the current and future trend of automobile development, so it is of great significance to develop and research the key technologies of electric vehicles. [0003] The vehicle controller (VCU) is the core of new energy vehicles, and is mainly responsible for coordinating the control between the engine management system (EMS) and the motor controller (MCU), power on and off management, comprehensive processing and reporting of system faults, etc. Reliability directly affects the reliability of new energy vehicles (such as electric vehicles), and is related to the safety of new energy vehicles. Therefore, before using the vehicle controller, it is necessary to test th...
