The present invention is a brake level indication device that indicates brake force applied by front vehicle driver to rear vehicle driver by switching ON and OFF series of LEDs or bulbs. It includes sensor which converts force applied to the brake in the form of variable electrical signal. The variable electrical signal is digitized into different levels by peripheral interface of microcontroller. The microprocessor processes the digitized data, depending on the level of output signal, turns ON the series of LEDs or bulbs. If full brake is applied, then all the bulbs or LEDs will be turned ON and also emergency flash light is turned ON. Providing braking information of front vehicle and indicating it to rear vehicle will reduce death rate due to vehicle collision.

A braking apparatus for a vehicle may include: a pedal stroke sensing unit configured to sense a pedal stroke of a brake pedal, and output a pedal stroke signal; and a control unit configured to control a brake actuator for braking the vehicle, based on the pedal stroke signal inputted from the pedal stroke sensing unit, and output a ramp signal in which information on whether a braking action of the vehicle has been performed is reflected, based on a reference voltage signal which is preset to determine whether the brake pedal is stepped on and a voltage signal converted from the pedal stroke signal.

Instead of binary brake lights on a car, the present disclosure provides methods and apparatus to provide an indicator of brake magnitude of the car. A pressure sensor, accelerometer, or other means of approximating the magnitude of a braking force are coupled to a control module, which itself is coupled to auxiliary lights mounted on the car. These auxiliary lights are capable of displaying a pulse, color, or a pattern correlated to the magnitude of the braking force. This gives drivers behind the car an indication of how quickly to respond to a braking car.

A brake lamp control method of a vehicle is provided. The method includes determining whether a deceleration of the vehicle based on regenerative brake through the electric motor is present in a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp. When the deceleration of the vehicle is present in the hysteresis period, the method includes determining a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period. In response to determining that the brake lamp is turned on or off for a reason except for the regenerative brake before the deceleration of the vehicle enters the hysteresis period, a request for turning on the brake lamp is set or reset based on the regenerative brake in response to the determined state of the brake lamp.

The disclosure relates to systems and methods for vehicle braking signals. In some embodiments, the present disclosure relates to a system and methods to improve the brake lights on automobiles.

The disclosure provides a hydraulic switch including a casing, a first cable, a second cable, an electrically conductive piston and a first magnetic conductive component. The casing has a chamber and a liquid channel connected to the chamber. The first cable is disposed through the casing, and the first electrical connection portion of that is located in the chamber. The second cable is disposed through the casing, and a second electrical connection portion of that is located in the chamber. The electrically conductive piston movably is disposed in the chamber. When the electrically conductive piston is in an electrically connected position, the electrically conductive piston is in electrical contact with the first electrical connection portion and the second electrical connection portion. The first magnetic conductive component is configured to provide a magnetic force to move the electrically conductive piston toward an electrically disconnected position.

Disclosed is a lamp switch for a parking brake and a structure of a lamp switch is configured to be changed, which indicates that a parking brake is pulled as lighting a lamp on a instrument panel of a vehicle by pulling a lever for the parking brake to prevent malfunction due to poor contact of the lamp switch when an external shock occurs, enhance fuel efficiency and reduce manufacturing cost due to weight reduction, and reduce the number of assembled fixtures.

A brake light control module for activating brake lights of a vehicle in response to activation of an engine brake of said vehicle. A control circuit of the module features a thyristor, a power lead and service lead for connection to the vehicle's electrical system and brake light service line across the thyristor, and a trigger lead for connection between the thyristor's gate terminal and an engine brake activation line of the vehicle to switch the thyristor to its conductive state when the engine brake activation line is energized. A delay circuit is installed in the power lead to prevent energization of the service lead in the event of a momentary gate signal indicative of an engine brake assisted gear shift. An operational indicator mounted within the housing is activated when the engine brake activation line is energized, thus confirming proper installation of the module.

In a method for monitoring the operational reliability of a braking system in a vehicle. A brake pedal actuation is monitored via a brake light switch. An error signal is generated if the brake light switch generates a switch signal, without a braking intent of the driver being registered via a sensor signal of a sensor.
