Abstract: A vehicle control device and a method thereof are provided. A master processor and a slave processor simultaneously receive, monitor or process signals of a vehicle, a power management module monitors the master processor via a first watchdog signal, and the master processor monitors the slave processor via a second watchdog signal. When the power management module sends the first watchdog signal to the master processor and no response message is received, the power management module sends a first reset signal to reset the master processor, and when the master processor sends the second watchdog signal to the slave processor and no response message is received, the master processor sends a second reset signal to reset the slave processor. When the master processor and the slave processor are abnormal, a forced wake-up module outputs a high level signal to forcibly wake up the master processor and the slave processor.

Abstract: Test equipment for a battery management system is provided. A battery-parameter recognition module measures a standard battery to obtain the first correction input, and uses the capacity test formula and the relaxation time test formula to perform a first charge and discharge test on the battery to be tested to obtain first battery parameter. A real-time simulation module determines the battery model and the simulated battery state based on the first battery parameter and the dynamic load. Each simulator of a physical signal simulation module provides a battery physical signal indicating the battery model. A connector provides the battery physical signal to the battery management controller under test. The battery management controller under test provides a stimulated battery state based on the battery physical signal. Master equipment compares the simulated battery state with an estimated battery state to determine whether the battery management controller under test is normal.

Abstract: A heavy vehicle brake control method includes: activating two electro-pneumatic proportional valve control modules to perform braking along a front-axle electrical brake loop and a rear-axle electrical brake loop, respectively; while the two electro-pneumatic proportional valve control modules perform braking along the front-axle electrical brake loop and the rear-axle electrical brake loop, judging malfunctions by detecting the two electro-pneumatic proportional valve control modules; if none of the malfunctions is detected, the two electro-pneumatic proportional valve control modules continuing to perform braking along the front-axle electrical brake loop and the rear-axle electrical brake loop; and, if one or more malfunctions are detected, then switching on a brake-pedal cable control module to control the brake pedal of the brake valve to perform braking. In addition, a heavy vehicle brake control device is also provided.
