Problems solved by technology

[0002] At present, there is no device on the car to indicate the running acceleration state to the rear. The driver of the car behind can only judge the acceleration or deceleration state of the car in front of him based on experience. Even experienced drivers often need to observe for a long time , to judge the acceleration and deceleration status of the vehicle in front, it cannot be monitored and judged

Embodiment Construction

[0021] figure 1 Among them, the integrated acceleration sensor chip (1) measures the acceleration value in the front and rear direction of the car, which contains the acceleration component due to the tilt of the car; the inclination angle; the signals measured by the above two chips are sent to the signal processing unit (3), and the signal processing unit calculates the acceleration component in the front and rear directions produced by the inclination angle, and then compares this component with the acceleration value detected by the acceleration sensor Add up to get the actual vehicle running direction acceleration value; then the data is sent to the display light-emitting array (4) for display. Considering the resolution ability of the human eye, data processing is performed every 0.1 second. The data processing unit is also responsible for determining the calibration data for the runtime tilt angle measurement when the vehicle is started.

Abstract

The invention relates to a display device which is mounted at the rear part of an automobile and displays an automobile operation acceleration towards the rear of the automobile to reduce or avoid accidents such as rear-end collision. An integrated acceleration sensor device for measuring the automobile operation acceleration, and an integrated gyroscope device or an integrated angle measurement device for measuring an inclination angle of the front and the rear of the automobile are mounted in the automobile acceleration display device; signals measured by the two devices are computed by a signal processing unit, so that a value of the acceleration of a practical automobile operation direction with an inclination influence eliminated is obtained, and sent to a display array to be displayed; the display array is formed by arraying two or more rows of luminous devices transversely or longitudinally; a positive (accelerating) data value and a negative (decelerating) data value of the acceleration are displayed by adopting luminous device arrays in different colors; the quantity of the illuminated luminous devices has a non-linear relationship with the accelerating and decelerating values; and the display device can calibrate the measured inclination angle.

Description

Technical field [0001] The invention relates to a device for displaying the running acceleration of a car, which is installed at the rear of the car and can display the acceleration (or positive or negative) information during the running of the car to the rear. Background technique [0002] At present, there is no device on the car to indicate the running acceleration state to the rear. The driver of the car behind can only judge the acceleration or deceleration state of the car in front of him based on experience. Even experienced drivers often need to observe for a long time , in order to judge the acceleration and deceleration status of the vehicle in front, it cannot be monitored and judged in real time. Existing automobile brake lights can indicate the braking action of the car driver, but cannot accurately reflect the change of the running acceleration of the car itself, especially the changing situation of the running acceleration of the car caused by power or road r...
