Vehicle emergency brake light control system

Abstract

A vehicle emergency brake light control system includes a control box installed in a car and electrically connected to the ABS (Anti-lock braking system), a car battery power supply, a throttle valve, a brake light, a third brake light and an emergency brake light of the car such that when the driver of the motor vehicle suddenly steps on the brake pedal to drive on the ABS, the control box is induced by a signal from the ABS to drive the brake light, the third brake light and the emergency brake light to flash; when the ABS is released and the vehicle driver steps on the accelerator pedal of the car to move the car again, the throttle valve gives a signal to the control box, causing the control box to turn off the brake light, the third brake light and the emergency brake light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, a vehicle emergency brake light control system in accordance with the present invention is shown comprising a control box 1 is shown installed in a motor vehicle, which has installed therein a ABS (Anti-lock braking system) 2, a car battery power supply 3 with a fuse-box 31, a throttle valve 4, a brake light 5, a third brake light 52, and an emergency brake light 6. The ABS (Anti-lock braking system) 2, the fuse-box 31 of the car battery power supply 3, the throttle valve 4, the brake light 5, the third brake light 52, and the emergency brake light 6 are respectively electrically connected to the control box 1. When the vehicle driver suddenly steps on the brake pedal to drive on the ABS 2, the control box 1 is induced by a signal from the ABS 2 to output a control signal to the brake light 5, the third brake light 52 and the emergency brake light 6, driving them to flash. When the emergency condition is eliminated and the ABS 2 is released and the vehicle driver steps on the accelerator pedal again, the throttle valve 4 gives a signal to the control box 1, causing the control box 1 to turn off the brake light 5, the third brake light 52 and the emergency brake light 6.

FIG. 3 is a system block diagram of an alternate form of the present invention. This embodiment is substantially similar to the aforesaid first embodiment with the exception of the additional car failure indicator light 51 and the exception that the throttle valve 4 is electrically connected to the control box 1 through the power distributor 7 of the vehicle.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.

Claims

1. A vehicle emergency brake light control system comprising a control box installed in a motor vehicle, said motor vehicle comprising a ABS (Anti-lock braking system) electrically connected to said control box, a car battery power supply electrically connected to said control box through a fuse-box, a throttle valve electrically connected to said control box, a brake light electrically connected to said control box, a third brake light electrically connected to said control box, and an emergency brake light electrically connected to said control box, wherein when the driver of the motor vehicle suddenly steps on the brake pedal to drive on said ABS, said control box is induced by a signal from said ABS to output a control signal to said brake light, said third brake light and said emergency brake light, driving them to flash; wherein said ABS is released and the vehicle driver steps on the accelerator pedal of the motor vehicle to move the motor vehicle again, said throttle valve gives a signal to said control box, causing said control box to turn off said brake light, said third brake light and said emergency brake light.

2. The vehicle emergency brake light control system as claimed in claim 1, wherein the motor vehicle further comprises a car failure indicator light electrically connected to said control box.

3. The vehicle emergency brake light control system as claimed in claim 1, wherein said throttle valve is electrically connected to said control box through a power distributor of the motor vehicle.
