The invention belongs to the technical field of traffic safety, and particularly relates to an automatic emergency brake control method. However, a current automatic brake control technology cannot give consideration to both early warning time and a safety distance. The invention provides the automatic emergency brake control method. The method comprises the steps of formulating an automatic emergency brake control strategy, wherein the automatic emergency brake control strategy includes an automatic emergency brake control algorithm, a hierarchical control system and a braking force distribution sub-strategy; judging collision danger according to front target motion information and own vehicle motion information, and giving early warning and braking operations; adopting a collision time algorithm in an early warning period, and adopting a safe distance algorithm in a to-be-braked period; sequentially transmitting control signals to a first-layer controller and a second-layer controller so that a control effect and expectation are kept consistent as much as possible; and generating a braking force through the braking force distribution sub-strategy so that automatic braking is achieved. And the safety is ensured, and meanwhile, over-urgent braking is avoided.

According to the electric auxiliary braking system and method for the hybrid electric vehicle, a driving motor assembly, a power generation system, a power battery assembly and an electric energy consumption box are all electrically connected with a high-voltage distribution box, and an electric energy consumption box switch is arranged between the high-voltage distribution box and the electric energy consumption box in series; the power battery assembly, the power generation system, the high-voltage distribution box, the electric energy consumption box switch, the conventional auxiliary brake switch, the ABS/ESC controller and the driving motor assembly are all in communication connection with the whole vehicle controller, and the conventional auxiliary brake switch is electrically connected with the conventional auxiliary brake system. According to the system and the method, it can be guaranteed that even if the power battery is fully charged, electric auxiliary braking can still play a role, the carried vehicle has the good long slope descending auxiliary braking effect, when the vehicle is driven to run through hybrid power, surge of the power battery is avoided during emergency braking, and normal work of the power battery is guaranteed.
