The invention provides an intelligent automobile tire pressure alarm system and an alarm method thereof, and the method comprises the steps: generating the steady-state excitation cost of tire pressure in a supersaturated state according to a tire pressure safety limit and an overpressure alarm compensation amount when the tire pressure is in the supersaturated state; generating the instability excitation cost of the tire pressure in the under-saturation state through the tire pressure safety limit and the under-pressure alarm compensation amount when the tire pressure is in the under-saturation state, and further determining the pressure risk trend of the tire pressure; determining a pressure tuning coefficient of tire pressure when the target intelligent automobile runs according to the static load information; and finally, determining a response decision quantity when the tire pressure alarm is triggered, and further carrying out dynamic alarm on the tire pressure. According to the scheme, the response decision-making amount when the tire pressure alarm is triggered is determined based on the pressure risk trend and the pressure tuning coefficient of the tire pressure, the triggering association capacity in the intelligent automobile tire pressure alarm can be improved, and joint recognition compensation during the intelligent automobile tire pressure alarm is achieved.
本申请提供了一种智能汽车轮胎压力报警系统及其报警方法,根据胎压安全界限和轮胎压力处于过饱和状态时的过压报警补偿量生成过饱和状态下胎压的稳态激励代价,通过胎压安全界限和轮胎压力处于欠饱和状态时的欠压报警补偿量生成欠饱和状态下胎压的失稳激励代价,进而确定轮胎压力的压力风险趋势;再通过静态载荷信息确定目标智能汽车在行驶时轮胎压力的压力调谐系数;最后确定触发轮胎压力报警时的响应决策量,进而对轮胎压力进行动态报警。上述方案基于轮胎压力的压力风险趋势和压力调谐系数确定触发轮胎压力报警时的响应决策量,可提高智能汽车轮胎压力报警中的触发关联能力,实现智能汽车轮胎压力报警时的联合识别补偿。
