我们在北京BJ212越野汽车上试装了转向讯响器,目的是当车辆在行车转弯前及转弯时讯响器随着转向讯号灯的明暗变化发出断续的音响讯号,使靠近车外的行人以及车内的人引起注意,车辆转弯注意安全。这样可以减少按喇叭的次数(或不按喇叭),同时又给司机的驾驶带来方便。另外讯响器所发出的声响(声压级)较低,只有近距离内才能听到因此对城市噪声的影响较小。
We installed a steering annunciator on the BJ212 off-road vehicle in Beijing. The purpose of the test was to signal the peephole and the vehicle near the vehicle as the vehicle sounded intermittent sound signals before and during the turning of the vehicle as the lights changed. People inside draw attention, turn the car and pay attention to safety. This reduces the number of speakers (or not), and at the same time gives drivers the convenience of driving. In addition, the sound emitted by the sounder (sound pressure level) is low, so it can be heard only at close range and therefore has less influence on the noise of the city.
