Embodiment Construction

[0030] figure 1 It is a functional block diagram of a vehicle alarm system in the present invention. like figure 1 As shown, a vehicle alarm system of the present invention includes at least one sensor 11 that collects the distance value between the motor vehicle and the obstacle; an alarm device 13 that sends out an alarm signal; and a controller 12, which includes an alarm threshold and a time threshold Storage unit 122, a timer 123 for measuring the duration of the distance value, a judging unit 124 for judging whether the distance value is less than the alarm threshold and whether the duration exceeds the time threshold, an indication unit for sending an alarm instruction to the alarm device 13 when the distance value is less than the alarm threshold 126, and an adjustment unit 125' for weakening the alarm signal when the distance value is less than the alarm threshold and when the duration of the distance value is greater than the time threshold. Wherein, the sensor 11 ...

Abstract

The invention discloses a vehicle alarm system, which comprises at least one sensor for collecting distance values ​​between motor vehicles and obstacles; an alarm device for sending out alarm signals; and a controller, which includes a storage unit storing alarm thresholds and time thresholds A timer for measuring the duration of the distance value; a judgment unit for judging whether the distance value is less than the alarm threshold and whether the duration is greater than the time threshold; an indication unit for sending an alarm instruction to the alarm device when the distance value is less than the alarm threshold; and when the distance value is less than An alarm threshold and an adjustment unit that instructs the alarm device to weaken the alarm signal when the duration of the distance value is greater than the time threshold. The vehicle alarm system can reduce the intensity of the alarm signal when the distance value between the motor vehicle and the obstacle continues to exceed a certain time. In this way, the driver of the motor vehicle will not feel bored because the warning signal does not change for a long time, thereby making it easier for the driver to drive.

Description

technical field [0001] The invention relates to an automobile auxiliary system, in particular to a vehicle alarm system installed on a motor vehicle. Background technique [0002] With the development of the economy, cars have become an indispensable means of transportation for people, and there are more and more people who have already bought a car or want to buy a car. Accompanying it is that the roads are becoming more and more congested, the parking space is becoming more and more narrow, and traffic accidents occur frequently. Even if car drivers have superb driving skills and highly concentrated attention, they cannot completely avoid traffic accidents, because drivers have visual blind spots when driving or parking, for example, drivers cannot see clearly behind the car. Happening. When the driver is reversing or driving a motor vehicle in a narrow passage, it is easy to have a collision accident, especially when the driver's driving level is not high. [0003] In ...
