Electronic devices called steer-by-wire sensors are used in steer-by-wire (SBW) systems to give input and feedback for a vehicle’s steering control. In conventional automobiles, a number of physical linkages and parts mechanically join the steering wheel to the wheels. In steer-by-wire systems, however, electrical impulses and sensors take the role of the mechanical link.
The use of steer-by-wire technology frees up more design and control options for vehicles by removing the necessity for a direct mechanical connection between the steering wheel and the wheels.
An essential function of the sensors in a steer-by-wire system is to translate the driver’s input from the steering wheel into electronic signals that the vehicle’s electronic control unit (ECU) can understand to regulate the steering mechanism.
Depending on how they are designed and implemented, steer-by-wire systems may use a variety of unique sensor types. However, these systems frequently use the following sensors:
Sensor for steering angle: This sensor gauges the angle of the wheel and picks up the driver’s input. It offers details regarding the intended course of the vehicle.
Torque sensor: This sensor gauges how much force or torque the driver applies to the steering wheel. It gives the system information about the driver’s aim and effort.
Position sensors: These sensors track the location and movement of different steering parts, including the steering rack, steering column, and electric motor. They aid in precisely monitoring and controlling the steering system.
Speed sensors: These sensors gauge how quickly the steering wheel or other important parts are rotating. They give the system data about steering dynamics, allowing it to modify steering reaction in accordance with vehicle speed.
Force sensors: In some cutting-edge steer-by-wire systems, forces acting on the steering system may be measured by force sensors. They are able to recognise outside disturbances, including wind forces or lane changes, and help with adjusting for them.
Together, these sensors give the electronic control system of the vehicle feedback and data in real time. In order to manage the steering mechanism and produce the correct steering response, the control system processes this information and then transmits the relevant signals to actuators, such as electric motors or hydraulic systems.
Overall, steer-by-wire sensors are crucial parts that allow for accurate and dependable steering control in vehicles with steer-by-wire systems, providing significant advantages in terms of safety, comfort, and flexibility in vehicle design.
The Global Steer-by-wire Sensors market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Hella intends to mass produce steering sensors for steer-by-wire systems that are entirely electric.
One of the first manufacturers to introduce steering sensors for by-wire applications into mass production was Hella. For the most recent generation of steering sensors, it has received numerous sizable customer orders. With the help of this crucial technology, Hella is greatly advancing the creation of steer-by-wire systems.
Hella’s electronics factories in Recklinghausen, Germany, and Xiamen, China, are anticipated to begin mass production in 2025 for a number of well-known clients. At the company’s headquarters in Lippstadt, Germany, development takes place.
Without the use of any mechanical or hydraulic connections, steer-by-wire systems deliver steering commands entirely electrically from the steering wheel to the front axle. In such a steering system, Hella’s steering sensors accurately and dependably measure the torque and angle of the steering wheel and transfer that information as an electrical signal.
The steering adjustment can be customised for the situation or the customer because no longer necessary mechanical components, like the steering rod, are required. The engine and interior of the vehicle can also be designed with flexibility, allowing for new sorts of cockpit designs, cost savings from modularization and variant reduction, as well as improved crash safety.
