Is There a Difference Between Auto Start-Stop and Auto Hold?

[LaWilliam]

Auto start-stop and auto hold are different, with the differences being: 1. Different meanings: Auto start-stop is a system that automatically turns off the engine when the vehicle comes to a temporary stop during driving and restarts it when needed to continue moving; auto hold is a feature where the vehicle can determine whether to apply the brakes automatically based on actual conditions. 2. Different functions: Auto start-stop controls the engine's start and stop; auto hold is equivalent to an electronic parking brake. The electronic parking brake is a technology that achieves parking braking through electronic control, working on the same principle as a mechanical handbrake—both use the friction generated between the brake disc and brake pads to control parking braking. The only difference is that the control method changes from the traditional mechanical handbrake lever to an electronic button.
