Abstract: A vehicle and a vehicle load distribution identification method and apparatus and a medium and electronic device. The identification method includes the steps of: acquiring (S31) a speed and longitudinal acceleration of the vehicle; when the longitudinal acceleration is less than an acceleration threshold, acquiring (S32) an actual driving force of the vehicle; obtaining (S33) the actual pitch angle of the vehicle according to the actual driving force and the vehicle speed; and obtaining (S34) load distribution of the vehicle according to the actual pitch angle. With this identification method, the difference between the front and rear axle loads of the vehicle can be identified by calculating the pitch angle of the vehicle, so that the vehicle load distribution can be identified without installing dedicated sensors such as a load sensor and a vehicle body height sensor at the vehicle suspension, which reduces the cost of vehicle load distribution identification and allows a wide range of applications without being limited by the vehicle model.

Abstract: A wheel-side reducer system includes a housing, a speed reduction assembly, and a steering knuckle. The housing includes a front housing and a rear housing. The front housing and the rear housing are arranged opposite to each other and define an accommodating space together. The speed reduction assembly is arranged in the accommodating space. The steering knuckle is integrally molded on the front housing. The integrally molding of the steering knuckle on the front housing not only simplifies the production process of the housing, but also makes a connection between the steering knuckle and the front housing more reliable. Meanwhile, the integration level of the wheel-side reducer system can also be improved, to reduce the size of the wheel-side reducer system. A vehicle with the wheel-side reducer system is further disclosed.
