Description

This application claims priority to Chinese Patent Application No. 202310922552.7, filed on July 25, 2023 and entitled "DRIVING FEEDBACK METHOD AND APPARATUS, AND VEHICLE-MOUNTED DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of automobile technologies, and in particular, to a driving feedback method and apparatus, and a vehicle-mounted device. BACKGROUND With development of electric vehicle technologies, electric vehicles are increasingly popular. After a driver changes from driving a fuel vehicle to driving an electric vehicle, driving inconvenience or even an accident is easily caused due to differences between pedal designs of the vehicles. There is a kinetic energy recovery system in the electric vehicle. Therefore, when an accelerator pedal is released, but the accelerator pedal still has an opening degree, the electric vehicle is in a deceleration state. This is different from the fuel vehicle, which is in the deceleration state only when a brake pedal has an opening degree. The foregoing differences between the electric vehicle and the fuel vehicle may result in poor driving feedback obtained by the driver when the driver drives the electric vehicle, and the driver easily mistakes the accelerator pedal for the brake pedal, which causes mistaken stepping on the accelerator pedal when braking is needed. SUMMARY This application provides a driving feedback method and apparatus, and a vehicle-mounted device. According to the method, an operation of a driver on a pedal can be fed back, and relationships between an operation, and auditory feedback and visual feedback are established for the driver. This enables the driver to be quickly familiar with vehicle operation and control logic, and strengthen proactive awareness and memory, which reduces a probability of mistakenly stepping on a throttle, and improves driving safety. According to a first aspect, this application provides a driving feedback method. The method includes: obtaining information about a pedal of a vehicle, where the information about the pedal includes information about an accelerator pedal and information about a brake pedal; and outputting vehicle status feedback information that matches at least one of the following: the information about the accelerator pedal and the information about the brake pedal, where the vehicle status feedback information indicates at least one of the following: a status of the accelerator pedal and a status of the brake pedal. In this implementation, the information about the pedal of the vehicle in a driving process is obtained, and then the vehicle status feedback information that can indicate at least one of the status of the accelerator pedal and the status of the brake pedal is output. In this way, an operation of a driver on the pedal can be fed back, and relationships between an operation, and auditory feedback and visual feedback are established for the driver. This enables the driver to be quickly familiar with vehicle operation and control logic, and strengthen proactive awareness and memory, which reduces a probability of mistakenly stepping on a throttle, and improves driving safety. In an implementation of this application, the information about the accelerator pedal includes a depth of stepping on the accelerator pedal, and the information about the brake pedal includes a depth of stepping on the brake pedal. In an implementation of this application, outputting the vehicle status feedback information that matches at least one of the following: the information about the accelerator pedal and the information about the brake pedal includes the following several cases. In a first case, when the depth of stepping on the accelerator pedal is greater than 0, and neither a traveling speed of the vehicle nor the depth of stepping on the accelerator pedal exceeds a corresponding threshold, first indication information is output, where the first indication information indicates that the accelerator pedal is in a power output state. The first case is a case in which the driver steps on the accelerator pedal and a stepping speed is slow, or a case in which the traveling speed of the vehicle is slow. In a second case, when at least one of a traveling speed of the vehicle and the depth of stepping on the accelerator pedal exceeds a corresponding threshold, second indication information is output, where the second indication information indicates that the accelerator pedal is in a high-power driving state. The second case is that an output power of the vehicle is high, and is represented as a case in which a vehicle speed is fast or the depth of stepping on the accelerator pedal of the vehicle is large. The traveling speed of the vehicle is obtained from a vehicle speed sensor in the vehicle. The second case familiarizes the driver with a cockpit feedback picture provided when the vehicle performs a high-power output. During normal dri
