Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The present invention has no special limitation on the specific location of the ultrasonic transceiver device. Multiple transceivers can be installed at different positions of the vehicle, or multiple ones with different directions can be installed at the same position. The following are the details of these two respectively.

[0026] Due to the good unidirectionality of the ultrasonic wave, we can consider that the transmitted wave hits the ground along the vertical direction, and due to the diffusion of the ground, the transmitted light can always be detected by the receiver installed at the same position as the transmitter take over. Therefore, within a large angle range, the ultrasonic transceiver device can always measure its distance from the ground. exist figure 2 and image 3 In , it shows that the present invention inst...

Abstract

The invention discloses a method and a device for measuring vehicle slope, which belongs to the fields of collection and processing of vehicle operating state parameters. The method comprises the following steps that a transmitting device is arranged on a vehicle and used for transmitting ultrasonic waves, a receiving device is arranged on the vehicle and used for receiving reflected waves, a distance H between each receiving device and the ground is determined according to reflected signals collected by the receiving device, and slope situations of a vehicle body are determined according to the relationship between the H value of each measurement point after denoising. The method and the device achieve the slope angle of the vehicle through the fact that the ultrasonic waves are adopted to measure the distance between a plurality of positions on the vehicle body and the ground, the ultrasonic waves are mature techniques, and the application of the ultrasonic waves reduces cost. The ultrasonic waves are good in unipolarity and high in precision of range measurement.

Description

technical field [0001] The invention relates to a method and a device for measuring vehicle inclination, belonging to the field of collection and processing of vehicle operating condition parameters. Background technique [0002] It is unavoidable that the vehicle will tilt during driving, generally, as long as the tilt is within the range allowed by the balance of the vehicle body, it is acceptable. For this reason, it is necessary to monitor the amount of inclination in real time. The primary problem in monitoring the amount of inclination is to measure the inclination parameters, and finally adjust the working status of the car according to the inclination parameters, including alarming and active braking in the case of anti-lock braking. At present, the measurement of tilt parameters is a relatively mature technology, and it has been applied to high-end vehicles, and the specific schemes adopted are different. For example, as shown in the invention patent entitled tilt...
