    1. Active Pedal - Clutch

    Modern systems like cruise-control, electrical parking brake, start-stop functions, start lock and torque adjustment require a displacement sensor on the clutch master cylinder. The displacement sensor measures up to 40 mm movement. Two-dimensional Hall-effect sensors are a robust and cost-effective solution for this task.

    2. Active Pedal - Acceleration

    Electronic throttle control replaces the mechanical link between acceleration pedal and throttle valve (drive-by-wire).

    Linear Hall sensors with analog output are used to detect pedal courses with small angle (<20°). They ensure reliability and high accuracy, especially to detect the accelerator idle position.

    Two sensors are always used for redundancy.

    3. Powertrain Valves - Throttle

    The throttle valve directly regulates the amount of air entering the engine (gasoline internal combustion engine) or is used to generate the intake manifold vacuum (diesel engine). Linear or 2D Hall sensors with analog output are used to detect throttle position. Sensors with integrated capacitor bring EMC robustness and system cost advantages

    4. Powertrain Valves - EGR

     

    EGR works by recirculating a portion of the engine’s exhaust gas back into the engine cylinders leading to reduced fuel consumption of the vehicle and less CO2 emissions. Sensors based on the 3D HAL technology provide an optimal solution for the measurement of the actual valve position being robust against air gap and temperature variations. Depending on requirements Linear sensors can also be used. Some modules are leadframe based and sensors with integrated capacitor bring EMC robustness and system cost advantages.

    5. Powertrain Valves - Thermal Valves

    Sensors based on the 3D HAL technology provide an optimal solution for the measurement of the actual valve position being robust against air gap and temperature variations.

    HVC all-in-one integrated solutions offer a very small footprint while matching the power requirement for a BLDC drive in a single chip without the need for external MOSFET. By this supporting the transition to an Intelligent Valve actuator.

    8. Gear position

    Commonly located on the automatic transmission, the gear position sensor communicates the gear shift’s position to the vehicle’s electrical system. A combination of several linear Hall sensors (up to 6) is deployed in each transmission. Analog or PWM output is required. Depending on the distance to be measured, linearization setpoints can be required.

    9. Water / oil pumps - BLDC Motor

    Hall switches are used for any type of pumps like for water and oil to detect the position of the impeller. To reduce the overall current consumption, the HAL 1502 3-wire version with only 1.6 mA is preferred. HVC products are also very well suited to provide efficient BLDC drives for types of pumps. Flexible solutions can be implemented in the area of Oil-, Water- and Fuel-pumps.
