AI Technical Summary
The existing 1-BOX braking system is prone to failure due to a single EPB design, which poses a high safety hazard.
The design employs a dual control module (master control module and slave control module), combined with dual power supply, dual drive modules and dual switching control chips, to achieve multi-layer redundancy in the control module, power level and power control level of the braking system, ensuring normal operation even in the event of a single point of failure.
This significantly reduces the probability of braking system failure due to a single point of failure, and improves the stability and safety of the braking system.
