Embodiment Construction

[0035] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0036] Such as Figure 1-2 As shown, a heating control method of a PTC heater for a vehicle, the PTC heater for a vehicle includes a plurality of heating pins; the heating control method includes steps:

[0037] S1. Receive heating control commands and output turn-on commands to each heating pin one by one;

[0038] S2. Detect whether the vehicle PTC heater reaches the preset maximum power, and if not, detect whether the temperature reaches the preset temperature;

[0039] S3. If the preset temperature is not reached, the fault number of the heating pins is detected, and the output states of the normal pins are recombined according to the fault number of the heating pins and the faulty heating pins.

Abstract

The invention relates to the technical field of vehicle heaters, and discloses a heating control method and system for a vehicle PTC heater, and the vehicle PTC heater comprises a plurality of heatingpins. The heating control method comprises the following steps: S1, receiving a heating control instruction and outputting a starting instruction to each heating pin one by one; s2, detecting whetherthe PTC heater for the vehicle reaches the preset maximum power or not, if not, detecting whether the temperature reaches the preset temperature or not; and S3, if the preset temperature is not reached, detecting the fault number of the heating pins, and recombining the output states of the normal pins according to the fault number of the heating pins and the fault heating pins. The invention hasthe advantages that the heating pins are started one by one, the peak current is low, and the safety is high; and the working states of the heating pins are detected, and when some heating pins fail,other normal pins can be recombined and used, so that the heating efficiency is high, and the temperature control is accurate.

Description

technical field [0001] The invention relates to the technical field of vehicle heaters, in particular to a heating control method and system for a vehicle PTC heater. Background technique [0002] With the gradual promotion and popularization of new energy vehicles, PTC electric heaters have been used more and more. PTC heaters for vehicles are devices that rely on electricity to assist in heating the compartment. PTC electric heaters use PTC thermistor elements as heat sources, among which, PTC thermistors are usually made of semiconductor materials, and the resistance of PTC thermistor elements changes with the ambient temperature, and its resistance value increases or decreases accordingly. Reduced change characteristics, so the PTC heater has the characteristics of energy saving, constant temperature, safety and long service life. [0003] Existing PTC heaters generally have the problems of low heating efficiency and inaccurate temperature control, and when some heating...
