Description

Brake warning system

This creation is about a brake warning system, especially one that has the effect of alerting the rear vehicle and is suitable for all types of vehicles.

At present, all kinds of vehicles are equipped with a third brake light according to the traffic rules, so that when the brake pedal is depressed, the vehicle can be constantly brightened by the third brake light in addition to the two rear brake lights. Display, so that the rear vehicle can see the driving condition of the vehicle ahead.

At present, the design of the illuminating lights of the smashing lights, whether it is a brake on the pedal of the brake pedal or an emergency brake on the brake pedal, is displayed in a constant light state. Therefore, when the speed is not fast, the front brake light is illuminated. Stepping on the brake pedal to carry out the reaction deceleration is still counted, and when driving on the highway and the speed is broken, the vehicle in front of the vehicle suddenly lights up, because it is impossible to tell that the front vehicle's brake light is on. The brake on the brake pedal or the emergency brake on the brake pedal is generally performed by first stepping on the brake pedal to react to the deceleration. However, when the vehicle in front is found to be the emergency brake on the brake pedal, it is necessary to increase the force to re-tread. When the pedal is braked, it is often too late to catch up with the vehicle in front.

Therefore, in view of the above-mentioned deficiencies, the present creator can propose a brake warning system with the effect of alerting the attention of the rear vehicle, so that the user can easily operate the assembly, and the research and design system is designed to provide user convenience. For the creative motives of the creators.

According to the start warning light signal, the braking time of the rear vehicle is increased to avoid the rear vehicle chasing the preceding vehicle due to the vehicle being out of reach, thereby increasing the overall utility.

The second purpose of this creation is to provide a brake warning system that outputs the double flash when the speed of the vehicle on the road before the vehicle is between 20 km (km/hr) and 80 km (km/hr). The start warning light signal of the circuit output is a flashing warning signal for the left and right lights of the vehicle, and the double flash is when the speed of the vehicle on the road is greater than 80 km (km/hr) before the vehicle is braked. The start warning light signal output from the light output circuit is a fast flashing warning signal for the left and right direction lights of the vehicle, and the rear vehicle can be alerted by different start warning light signals at different driving speeds. Note that it is convenient for the rear vehicle to judge the speed of the preceding vehicle according to different starting warning lights, and quickly react to step on the brake pedal to maintain a safe distance with the preceding vehicle, thereby increasing the overall visibility.

In order to achieve the above objectives, the brake warning system of the present invention comprises: a vehicle body integrated device and a brake controller, which is capable of receiving a vehicle traveling on a road and driving the vehicle after the brake pedal is depressed. Driving speed after braking, and the vehicle body integrated device can control left and right direction lights of the vehicle; and the brake controller and the body set A digital signal conversion circuit and a double flash output circuit are disposed between the devices, and the brake controller transmits the vehicle speed of the vehicle on the road and the brake through the digital signal conversion circuit. And driving the vehicle speed, and the braking controller performs the vehicle speed on the road after the vehicle is traveling on the road, and subtracts the traveling speed of the vehicle to obtain a sharply reduced vehicle speed, and when the vehicle is When the sharply reduced vehicle speed is greater than a set value, the brake controller outputs a start warning light signal to the vehicle body integrated device through the double flash light output circuit according to the vehicle speed running on the road before the brake, so that the vehicle body integrated device can The left direction light and the right direction light of the vehicle are controlled according to the start warning light signal to perform an alert.

Please refer to Figures 1~4, which are schematic diagrams of the present embodiment, and the brake warning system of the present invention is mainly applied to various vehicles to have the effect of warning the attention of the rear vehicle, and can increase the braking strain of the rear vehicle. Time, to avoid the rear vehicle chasing because of the car Vehicle ahead.

The brake warning system of the present invention is mainly disposed on the vehicle, and includes a body integrated device 10 and a brake controller 20, wherein the body integrated device 10 is composed of an integrated controller, an in-vehicle network control system, and a vehicle speed signal. The sensor, the directional light switch signal sensor, the brake light signal sensor (not shown), the integrated controller is connected to the vehicle speed signal sensor through the vehicle network control system, the direction light switch signal sensor, the brake light Signal Sensor Other signal sensors transmit the vehicle speed signal, the direction light switch signal, the brake light signal, etc. to the integrated controller, and the vehicle network control system is a multimedia guided transmission system (MOST), a control area network. Any one of CAN Bus, LIN Bus, and Flexray. Therefore, the vehicle body integrated device 10 can receive the vehicle speed 51 on the road through the integrated controller and the vehicle speed 52 after the vehicle is generated after the brake pedal is depressed (as shown in FIG. 1). Moreover, the body integrated device 10 can also control the left-side lamp 61 and the right-direction lamp 62 of the vehicle to perform an operation of turning on or off the light through the integrated controller.

The brake controller 20 is connected to the vehicle body integration device 10, and a digital signal conversion circuit 30 and a double flash output circuit 40 are disposed between the brake controller 20 and the vehicle body integration device 10 (such as the first As shown in the figure, the brake controller 20 can capture the vehicle speed 51 of the vehicle on the road and the vehicle speed 52 after the vehicle through the digital signal conversion circuit 20, and The vehicle speed 51 on which the vehicle travels on the road and the vehicle speed 52 after the vehicle are converted into digital signals for being supplied to the brake controller 20 for processing and calculation to enable braking control.

And the brake controller is pressed when the vehicle is stepping on the road while driving the brake pedal 20 will first judge whether it exceeds 20 km (km/hr) according to the speed 51 of the vehicle on the road. When the vehicle speed exceeds 20 km (km/hr), the brake controller 20 carries out the vehicle. The vehicle speed 51 on the road minus the driving speed 52 after the braking to obtain a sharply reduced vehicle speed, and when the vehicle's sharpening speed is greater than a set value, the braking controller 20 will drive on the road according to the braking vehicle. The vehicle speed 51 outputs a start warning light signal 41 to the body integrated device 10 (shown in FIG. 1) through the double flash output circuit 40, so that the body integrated device 10 can be controlled according to the start warning light signal 41. The left direction light 61 and the right direction light 62 of the vehicle are alerted, wherein the set value is set within a range of 5 kilometers (km/hr) to 15 kilometers (km/hr).

The brake controller 20 of the present invention has a two-stage mode of the speed 51 driving on the road, wherein the speed 51 of the road before the brake is located at 20 km (km/hr) to 80 km (km/hr). The start warning light signal 41 outputted by the double flash output circuit 40 is a flashing warning signal of the left direction light 61 and the right direction light 62 of the vehicle (as shown in FIG. 3), that is, The flashing warning interval is from 0.3 seconds to 0.5 seconds to warn the rear vehicle to pay attention to the deceleration.

The other stage mode is that when the speed 51 of the vehicle driving on the road is greater than 80 kilometers (km/hr), the start warning light signal 41 outputted by the double flash output circuit 40 is the left direction light of the vehicle. And the right direction light 62 performs a fast flashing warning signal (as shown in FIG. 4), that is, the flashing warning interval is a fast flashing interval of about 0.1 second to about 0.3 seconds to warn the rear vehicle to react quickly and Slow down to prevent it from hitting the front.

In addition, the creation is based on the set value of 10 km (km/hr). When the speed 51 of the vehicle on the road is 70 km (km/hr), the vehicle is produced after the brake pedal is depressed. The driving speed 52 after the brake is generated is 57 (km/hr), and the braking controller 20 is used to subtract the two to obtain the sharply reduced vehicle speed of 13 (km/hr). Therefore, when the sharply reduced vehicle speed is 13 (km/hr) exceeding the set value is 10 km (km/hr), and the vehicle speed 51 on the road before the brake is 70 km (km/hr) is falling on Between 20 km (km/hr) and 80 km (km/hr), the start warning light signal 41 outputted by the double flash output circuit 40 is a flashing warning for the left direction light 61 and the right direction light 62 of the vehicle. The signal, that is, the flashing warning interval is about 0.3 seconds to 0.5 seconds, so that the rear vehicle can prepare to slow down after seeing the flashing warning.

When the start warning light signal 41 in the above two-stage mode is illuminated, it will continue to operate for about 10 seconds to 15 seconds, and when the body integrated device 10 detects the left direction light switch 53 and the right direction light that switch the vehicle. When the signal of the switch 54 or the signal of the accelerator pedal 55 of the vehicle is accelerated (as shown in FIG. 1), the flashing warning or quick flashing warning of the activation warning light signal 41 is immediately released to facilitate The rear vehicle can clearly see the situation.
