1. An anti-dive control method for an automobile, comprising:
obtaining a parameter value of a preset automobile operating condition parameter in real time;
determining in real time whether the parameter value of the automobile operating condition parameter satisfies a preset first trigger condition or a preset second trigger condition;
obtaining a preset first control strategy corresponding to the first trigger condition, in response to that the parameter value of the automobile operating condition parameter satisfies the preset first trigger condition;
controlling a suspension damping force of the automobile in real time according to the first control strategy;
obtaining a preset second control strategy corresponding to the second trigger condition, in response to that the parameter value of the automobile operating condition parameter satisfies the preset second trigger condition; and
controlling the suspension damping force of the automobile in real time according to the second control strategy;
wherein controlling the suspension damping force of the automobile in real time according to the first control strategy comprises:
obtaining a preset first set of operating condition parameters corresponding to the first trigger condition, and obtaining each parameter value of the first set of operating condition parameters in real time;
querying damping forces mapped to the each parameter value of the first set of operating condition parameters, and taking a largest damping force from the queried damping forces as a first damping force;
obtaining each emergency deceleration operation condition triggered by each emergency deceleration trigger signal;
querying damping forces mapped to each triggered emergency deceleration operating condition, and taking a largest damping force from the queried damping forces as a second damping force; and
taking a larger one of the first damping force and the second damping force as a target damping force control amount, and controlling the suspension damping force of the automobile in real time according to the target damping force control amount.
