Embodiment Construction

[0030] Fig. 1 is a functional block diagram of a vehicle alarm system of the present invention. As shown in Figure 1, a kind of vehicle warning system of the present invention comprises at least one sensor 11 that gathers the distance value between motor vehicle and obstacle; Send the warning device 13 of warning signal; The storage unit 122 of the time threshold, the timer 123 measuring the duration of the distance value, whether the judging unit 124 for judging whether the distance value is less than the alarm threshold and the duration exceeds the time threshold, sends an alarm command to the alarm device 13 when the distance value is less than the alarm threshold An indication unit 126, and an adjustment unit 125' that weakens 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 is connected with the controller 12 through the sensor interface 121 .

Abstract

The present invention discloses a vehicle alarm system. Said vehicle alarm system includes the following several portions: at least one sensor for collecting distance value between the motor vehicle and obstruction, alarm device capable of giving out alarm signal and controller. Said controller includes storage unit for storing alarm threshold value and time threshold value; timekeeper for measuring sustained time of distance value; judgement unit for judging that the distance valve is less than alarm threshold valve or not and the sustained time is greater than time threshold value or not; indication unit capable of giving out alarm instruction to alarm device when the distance value is less than alarm threshold value; and regulation unit for making alarm device weaken alarm signal when the distance value is less than alarm threshold value and the sustained time of distance value is greater than time threshold value.

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 ...
