The invention relates to the technical field of vehicle control, and discloses a vehicle turning alarm method, device and system. The method comprises the following steps: obtaining a first speed signal of a left wheel of a vehicle and a second speed signal of a right wheel of the vehicle in real time; comparing the first speed signal and the second speed signal, and when it is continuously detected that the first speed signal is smaller than the second speed signal, determining that the vehicle enters a left turning state, and giving a left turning alarm; and when it is continuously detected that the first speed signal is larger than the second speed signal, determining that the vehicle enters a right-turning state, and giving right-turning alarm. The method, the device and the system have the beneficial effects that the first speed signal and the second speed signal are obtained to serve as logic decision bases of turning alarm, and dependence on the driving state of a driver is avoided; the first speed signal and the second speed signal are adopted, a steering wheel angle sensor does not need to be additionally arranged, cost is low, and popularization is easy; and a decision is made according to the size of the first speed signal and the second speed signal in a continuous range, so that turning alarm reminding is more accurate.
本发明涉及车辆控制技术领域,公开了一种车辆转弯报警方法、装置和系统,所述方法包括:实时获取车辆左轮的第一速度信号和车辆右轮的第二速度信号;比较第一速度信号和第二速度信号的大小,当连续检测到第一速度信号小于第二速度信号时,确定车辆进入左转弯状态并进行左转弯报警;当连续检测到第一速度信号大于第二速度信号时,确定车辆进入右转弯状态并进行右转弯报警。有益效果:获取第一速度信号和第二速度信号作为转弯报警的逻辑决策基础,避免对驾驶员驾驶状态的依赖;采用第一速度信号和第二速度信号不需要加装方向盘转角传感器,成本低,易推广;根据第一速度信号和第二速度信号在一个连续范围的大小进行决策,使转弯报警的提醒更加准确。
