Problems solved by technology
[0003] In related technologies, detection is mainly performed manually, for example, the road test detection method, that is, the braking system of the vehicle is tested on the actual road through a real driving environment. However, since this method is manually tested, therefore, When the abnormality of the vehicle's braking is relatively mild, it is difficult to accurately determine whether the vehicle's braking is abnormal

Embodiment Construction
[0028] Specific embodiments of the present disclosure will be described in detail below. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0029] The application scenario of the present disclosure is first described. At present, a wheel speed sensor is installed on a wheel of a vehicle to measure the rotational speed of the vehicle wheel. The wheel speed sensor is composed of a sensing head and a ring gear. The sensing head is composed of a permanent magnet, a Hall element or an electronic circuit. The ring gear is installed on the hub or axle of the wheel and rotates with the wheel. When the wheel rotates, the ring gear synchronous with the wheel also rotates together. During the rotation of the ring gear, the bumps on the ring gear change the magnetic field formed by the sensing head, thereby generating a rotation pulse signal. One bump ...

The invention relates to a vehicle braking monitoring method and device, a vehicle and a storage medium. In a current braking period, a first rotation pulse signal and a second rotation pulse signal of the vehicle are acquired, the first rotation pulse signal is a pulse signal generated in the rotation process of a gear ring of a first wheel of the vehicle, and the second rotation pulse signal isa pulse signal generated in the rotation process of a gear ring of a second wheel of the vehicle; the braking period includes the time from the moment when the vehicle enters in a braking state to themoment when the vehicle exits the braking state; a first number of the first rotation pulse signal and a second number of the second rotation pulse signal are obtained; a first difference value of the first number and the second number is calculated; and when it is confirmed that the first difference value is larger than or equal to a first preset threshold value, an abnormal wheel in the first wheel and the second wheel is confirmed according to the first number and the second number.
Description
technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a vehicle braking monitoring method, device, vehicle and storage medium. Background technique [0002] The braking system of the vehicle can control the vehicle to slow down or stop according to the driver's request, or ensure the safe parking of the vehicle, so as to ensure the safety of the vehicle and the driver. Therefore, it is of great significance to determine whether the braking system of the vehicle is normal. [0003] In related technologies, detection is mainly performed manually, for example, the road test detection method, that is, the braking system of the vehicle is tested on the actual road through a real driving environment. However, since this method is manually tested, therefore, When the braking abnormality of the vehicle is relatively mild, it is difficult to accurately determine whether the braking of the vehicle is abnormal.
