Problems solved by technology

Among them, the reversing radar system is the most widely used. The reversing radar system aims to provide the driver with the distance information of the obstacles around the vehicle in time during the parking process. If the system response time is too slow, there may be a risk of hitting an obstacle.

Embodiment Construction

[0017] The following combination Figure 1~5 , the content of the present invention will be described in detail through specific embodiments. A detection device for the response time of a parking radar system, which consists of two subsystems, mechanical and electrical, wherein the mechanical subsystem includes a trigger mechanism and a motion structure. The trigger mechanism is composed of a bracket, a slideway, a rotating shaft, and a water pipe. Composed of driving wheels and driven wheels, the detection platform of the mechanical system has a rectangular bottom plate at the bottom, two driven wheels parallel to the short sides of the rectangle are set on the right side of the bottom plate, and there is a driving wheel on the upper limit of the other short side of the rectangle. A traveling motor is installed on the driving wheel, and a slideway is provided on each of the two long sides of the rectangular bottom plate. The top of the slideway is connected by a bracket. The...

Abstract

The invention relates to a detection device of reaction time of a reverse radar system. The detection device is composed of a mechanical sub system and an electrical sub system to realize the functionof dynamic and static evaluation of reaction time of a reverse radar system. The mechanical sub system consists of a trigger mechanism and a movement structure; and the trigger mechanism includes a bracket, a sliding way, a rotating shaft, and a water pipe. The electrical sub system includes a control module with a control board formed by an MCU, an alarming sound pick-up module formed by a transmitter and an audio amplifier A1, and a display module formed by a Nixie tube and a drive circuit thereof. A marching motor M1, a trigger motor M2, and driving circuits thereof form an execution mechanism, wherein R1, R2, and Q1 are drive circuits of the M1 and R21, R22, and Q2 are drive circuits of the M2. Keys SW1 and SW2 and a travel switch J1 form a trigger module. The detection device has thefollowing advantages: reaction time of the reverse radar system can be measured and outputted visually; the accuracy of measurement is improved; the measurement time is shortened; and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a detection device for the response time of a parking radar system. Background technique [0002] Due to the characteristics of reliable operation, accurate ranging, and low cost, ultrasonic sensors are widely used in automotive reversing radars, automatic parking systems, and other fields. Among them, the reversing radar system is the most widely used. The reversing radar system aims to provide the driver with the distance information of the obstacles around the vehicle in time during the parking process. If the system response time is too slow, there may be a risk of hitting an obstacle. Due to the different design schemes of each system, the reversing radar system sounds through its own speaker, some through the speaker or buzzer of the instrument, and some transmit the distance information to the vehicle multimedia system through the vehicle network, and make the sound...
