Automotive steering torque sensor is a part of electric power steering system that measures torque over steering wheel. This sensor records the torsion bar angle that is required for steering movement. Two main types of torque sensors found in electronic power steering systems are contact torque sensors and non-contact torque sensors
Market Dynamics:
Increasing demand for advanced, high-performance vehicles due to increasing fuel prices is one of the major factors propelling demand for steering torque sensors in the automotive sector. Electric power systems help to reduce fuel consumption. For instance, according to a press release of Robert Bosch Gmbh on June 2015, electric power steering system saves 0.6 liters of fuel in 100 km compared to hydraulic power steering system. The press release also stated that electric power steering system produces 16.1 g/km less carbon dioxide compared to hydraulic power steering system. These benefits influence car manufacturer to replace hydraulic steering system technology with electric power system. Therefore, increasing installation of electric power systems propel demand for steering torque sensors. Steering torque sensors measure torque that driver applies to the steering wheel. The data is transferred to Electronic Control Unit (ECU) that monitors the overall speed of the vehicle. ECU later calculates the assisting torque that is required to be applied and accordingly signals the assist unit i.e. motor to apply the desired torque to steering gear. Therefore, these factors are expected to propel demand for steering torque sensors over the forecast period.
