Description

Vehicle acceleration and deceleration indicator

The present invention relates to an acceleration and deceleration display device for a vehicle. In particular, the acceleration and deceleration display is integrated on the speedometer installed in the front panel of the driver's seat so that the driver can directly check the degree of acceleration and deceleration as well as the driving speed of the vehicle. By doing so, it is possible to increase the fuel efficiency and stability of the vehicle through appropriate acceleration and deceleration.

In general, the instrument cluster in front of the driver's seat has a speedometer indicating the speed of the vehicle per hour, an ammeter indicating the magnitude of the current discharged from the battery and the magnitude of the current charged from the generator, and the hydraulic pressure indicating the oil pressure in the engine. Various instruments are provided, such as a fuel gauge indicating the amount of fuel in the fuel tank, and a water thermometer indicating the temperature of the engine cooling water.

As shown in FIG. 1, a speedometer, which is one of the instruments provided to enable the driver to easily grasp the situation of the vehicle with the eyes while driving, to safely drive the vehicle while maintaining the optimum state, is illustrated in FIG. 1.

That is, the conventional speedometer shown in Fig. 1 shows a speed indicator 1 indicating the speed of an automobile per hour, a totalizer 2 indicating the total driving distance, and a distance traveled by turning it to "0" from time to time. Combination with the range odometer (3), so that the driving speed and the distance of the car can be seen at a glance.

However, since the conventional vehicle is not equipped with a device for displaying acceleration and deceleration which affects vehicle fuel economy and vehicle safety, it is not possible to know an appropriate acceleration and deceleration limit of the vehicle that can improve the fuel economy and stability of the vehicle. .

In this way, if the driver drives without knowing the proper acceleration and deceleration, the driver is driven by the sense of speed based on his driving experience. Therefore, the driver is often driven by rapid acceleration and deceleration. As a result, the fuel economy of the vehicle is deteriorated, and there is a problem in that the driving stability of the vehicle on the curve road is lowered.

An object of the present invention is to solve the above problems, by allowing the driver to directly check the degree of acceleration and deceleration of the vehicle by allowing the driver to travel at an appropriate acceleration and deceleration, fuel economy and stability of the vehicle To provide a vehicle acceleration and deceleration display device to improve the.

In order to achieve the above object, the present invention includes an acceleration sensor mounted at the center of the vehicle body, or in the case of a vehicle equipped with the wheel speed sensor, the wheel speed measured by the wheel speed sensor may be integrated in the electronic controller to measure acceleration and deceleration speed. And display devices indicative of the accelerations and decelerations measured above in parallel to the speedometer.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail the configuration and operation effects as follows.

In the above configuration, in the case of a vehicle equipped with a wheel speed sensor, the measurement device integrates the wheel speed measured by the wheel speed sensor in an electronic control unit. It does not matter which one adopts the method of measuring the acceleration and deceleration, but it should be equipped with a device that can measure the acceleration and deceleration.

In addition, the acceleration and deceleration display device (A) is disposed in parallel with the totalizer (2) and the sectional distance meter (3) on the speedometer of the instrument cluster in front of the driver's seat, the driver according to the signal sent from the measuring device acceleration and deceleration The acceleration and deceleration states are displayed by using the light emitting body 4 (LED;

At this time, the light emitter 4 displays the acceleration section and the acceleration / deceleration section by different colors (for example, acceleration: blue, deceleration: red), and also increases the absolute value displayed in each section. 4) Change the color density to increase clarity.

In addition, the appropriate limit of acceleration and deceleration considering fuel efficiency and vehicle stability is classified into appropriate deceleration area 5 and appropriate acceleration area 6 respectively on the outer edge of the light emitting body 4 according to the vehicle. And deceleration can be maintained.

Therefore, when the acceleration and deceleration display device A is arranged in parallel with the speed indicator 1 of the speedometer of the vehicle, the driver can easily grasp not only the driving speed but also the current acceleration and deceleration while driving. Not only can the stability of the vehicle be secured, but the vehicle's fuel economy can be improved through proper acceleration and deceleration.

As described above, according to the present invention, there is provided a measuring device capable of measuring acceleration and deceleration, and the display device indicating acceleration and deceleration according to the signal sent from the measuring device is arranged in parallel on the speedometer. By increasing the clarity by using the color and density of the light emitting device as a display method of the display device, the driver can easily grasp the acceleration and deceleration speed along with the driving speed while driving, thereby promoting safe driving of the vehicle. Therefore, the appropriate acceleration and deceleration area is marked so that fuel economy can be improved.
