What does the 'a' behind the handbrake mean?

[LaCarter]

The 'a' behind the electronic handbrake stands for the Auto-Hold system, which is a technology application that enables automatic handbrake function during vehicle operation. This technology allows drivers to avoid prolonged braking when the vehicle is stationary, and prevents unnecessary vehicle sliding when the automatic electronic parking brake is activated. Here is more information about the Auto-Hold system: 1. The function of the Auto-Hold system is to prevent the vehicle from rolling backward, making it particularly useful on slopes and during frequent starts and stops. The Auto-Hold system and the electronic handbrake together form an intelligent brake control system. 2. It integrates the temporary braking during driving with the long-term braking after parking, and achieves parking brake through electronic control.
