This application discloses a signal sending method. When a user triggers an event of a first icon, a system on chip SOC of a vehicle host generates a high-speed serial signal and sends the high-speed serial signal to an instrument panel, the high-speed serial signal is used to transmit a window image corresponding to the first icon, and the instrument panel includes a deserializer, a microprocessor MCU, and a display, and the method includes: The MCU receives a first image signal sent by the deserializer, where the first image signal is obtained after the high-speed serial signal is parsed. The MCU obtains a first check value based on the first image signal. When detecting that the first check value is different from a second check value corresponding to the first icon, the MCU sends a second image signal to the display. The method disclosed in this application may be applied to an intelligent vehicle, an autonomous vehicle, an electric vehicle, or a new energy vehicle. When it is detected that the first image signal is subject to interference, the second image signal is sent, so that a normal window image including the first icon is displayed on the display, to improve driving safety of a driver.
