Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

Referring to fig. 1 and 2, a schematic diagram of an embodiment of a vehicle handbrake take-up to position prompting device 100 and a slope calculation schematic diagram are respectively shown. A gradient sensor is shown, wherein the gradient sensor has an arc-shaped ball track 3 with a radius R, wherein distance sensors 4 are arranged at both ends of the ball track 3, wherein a ball 2 with a radius R is arranged in the ball track 3, wherein the ball 2 can freely roll in the ball track 3, and wherein the distance sensors 4 are used for measuring the distance L from the center of the ball 2. It goes without saying that the distance sensors 4 together represent two, i.e. two measurements of different sizes can be obtained, and R is greater than R. That is to say, the gradient sensor adopts the symmetrical design, and position sensors are placed on both sides. Whereby the car is parked on an upward or downward slope and the ball 2 rolls over the position-biased sensor, both sensors detecting position information. In addition, in an embodiment not shown in the figures, stops are also arranged at each end of the ball track 3 in order to prevent the balls 2 from falling out of the ball track 3.

a. when the vehicle is parked on a slope, the balls 2 roll to a low point in the ball track 3 and are stationary, that is, in a balanced state;

b. the distance sensor 4 measures the distance L between the distance sensor and the center of the ball 2, so as to position the ball and determine the gradient;

c. the signal converter 5 takes the distance L and takes a smaller value therefrom (two differently sized measured values in the case of a ramp, due to the two distance sensors) and in turn according to the following equation

Calculating the slope a of the ramp and converting it into a control signal;

d. the handle driver 6 acquires the control signal and adjusts the handle 7 and the cue tone generator 8 to corresponding positions at the gradient (the larger the value of alpha is, the larger the clockwise rotation angle of the handle 7 is, namely, the larger the stroke of the vehicle hand brake pull rod 9 is needed to touch the cue tone generator 8);

e. pulling the hand brake pull rod 9 makes the hand brake pull rod 9 move along the ratchet wheel until it touches the prompting tone generator 8, the prompting tone generator 8 sends out the prompting tone to prompt the hand brake pull rod 9 is in place, thereby ensuring that the automobile can not slide on the slope, and preventing the hand brake cable from being stressed too much to reduce the service life of the hand brake cable.

In a preferred embodiment, in order to remind a driver to operate the vehicle handbrake pull rod 9, an alarm device is further arranged on the vehicle handbrake body 1 and used for sending alarm information before the vehicle handbrake pull rod 9 touches the prompt tone generator 8, and meanwhile, the alarm information is different from the prompt tone in alarm sound so as to be distinguished.
