The following solutions demonstrate the diverse applications of relays in automotive electronics systems to enhance vehicle safety, functionality and ease of operatioy.
.
1. Power Door and Window Control
- Programme Description: A bidirectional relay is used to control the forward and reverse rotation of the window motor to achieve up and down movement of the window. The current direction is switched by the switching state of the relay to control the opening and closing of the windows.
- Advantage: Improves the response speed and reliability of the power windows and doors and extends the life of the motor.
2. Car Light Control
- Programme description: Relays are used to control the current flow of headlights, taillights, fog lights and turn signals. Especially in high current situations, the relays relieve the burden on the switch.
- Advantage: It improves the stability and safety of the lights and protects the circuit from current shock.
3. Electric Window Defrost
- Programme description: Using a relay to control the energisation and de-energisation of the electric heating wire, the relay automatically controls the window defrost according to the sensor detection results.
- Advantage: Automatic control improves driving safety and reduces energy consumption.
4. Air-conditioning Compressor Control
- Programme Description: Controls the start and stop of the air-conditioning compressor through a relay. When the interior temperature reaches the set value, the relay cuts off the compressor power to save energy.
- Advantage: Improves the efficiency of the air-conditioning system and extends the service life of the compressor.
5. Starting motor control
- Programme description: The relay controls the operation of the starter motor when the vehicle is ignited, and is able to withstand the high current at the moment of starting to ensure the stable operation of the starter motor.
- Advantage: Improves the reliability of vehicle starting and reduces the load on the battery.
6. Safety system control
- Programme Description: Relay is used to control the airbag triggering mechanism. When the sensor detects a collision, the relay responds quickly to activate the airbag.
- Advantage: It improves the response speed of the safety system and ensures the safety of the occupants.
1. Fuel pump control
- Programme description: The relay is used to control the start and stop of the fuel pump. When the ignition is on, the relay switches on the fuel pump circuit to ensure smooth fuel supply to the engine.
- Advantage: High reliability and ensures stable fuel supply when the engine starts.
2. FAN CONTROL
- Programme description: The relay is used to start or stop the engine cooling fan, adjusting the fan working status in real time according to the engine temperature to ensure that the engine operates within the optimal temperature range.
- Advantage: It extends the life of the engine and fan and reduces unnecessary energy consumption.
1. FAN CONTROL
- Programme description: Relays are used to start or stop the cooling fans, adjusting the fan operating status in real time according to the temperature of the equipment and ensuring that the equipment operates within the optimum temperature range.
- Benefits: Extends the service life of the equipment and fans and reduces unnecessary energy consumption.
2. Electric Vehicle Charging Management
- Programme description: In the EV charging system, relays are used to control the connection between the charger and the battery, monitor the charging status and avoid overcharging or undercharging.
- Benefits: Improved safety of the charging process and extended battery life.
