Document Type and Number:
WIPO Patent Application WO/2021/082915
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to the technical field of automobiles, and disclosed is an automobile key programmer which is applied to an automobile diagnostic instrument. The automobile key programmer comprises an activation coil, a first diverter switch, a second diverter switch, an infrared modulation circuit, an amplitude shift keying modulation circuit and a frequency shift keying modulation circuit. When the first diverter switch is not powered on, the infrared modulation circuit supplies a resonant voltage to the activation coil; when the first diverter switch is powered on and the second diverter switch is not powered on, the amplitude shift keying modulation circuit supplies a resonant voltage to the activation coil; and when both the first diverter switch and the second diverter switch are powered on, the frequency shift keying modulation circuit supplies a resonant voltage to the activation coil. In the automobile key programmer provided in the embodiments of the present invention, only one coil is needed to switch between three resonance voltages so as to solve the needs of different types of keys for coils.
