Vehicle Electrification Market Trends

Key Emerging Trends in the Vehicle Electrification Market

In recent years, more cars with electric power steering have been sold. Electric power steering is better for saving fuel because it doesn't use as much energy as the traditional hydraulic power steering. Most cars used to have hydraulic power steering, which relies on pistons and pressurized fluid in the steering rack. A pump, powered by the car's engine, maintains fluid pressure. On the other hand, electric power steering doesn't use pistons and pumps. Instead, it has a single motor that pushes the steering rack. Electric power steering uses energy only when you turn the wheel, while hydraulic power steering uses energy all the time. According to German carmaker ZF Lenksysteme, electric power steering uses 90% less energy than hydraulic steering, which means it helps cars use less fuel.

According to data from the International Organization of Motor Vehicle Manufacturers (OICA), cars with electric power steering made up 83% of the market share in 2015. This is because they use less fuel and power. Car manufacturers and suppliers are investing in new technologies for steering. In developed countries like North America and Europe, high-end consumers want advanced technologies, leading to a high demand for electric power steering. Companies like JTKET Corporation are creating new products, such as dual pinion assist.

Advances in technology and software allow engineers to create systems that give drivers a better feel for controlling and steering the wheels. For example, Dual Pinion Electric Power Steering (EPS) is being developed. It optimizes the primary pinion for vehicle dynamics and performance, while the secondary pinion assists. This design flexibility allows the motor, controller, and assist mechanism to be placed opposite the driver's side under the hood. These improvements enhance driver comfort and provide a premium steering feel.

Electric power steering is replacing hydraulic power steering mainly because it is more efficient. The electric motor replaces the piston and pump and draws electricity from the battery. Installing this system on the assembly line is easier because there are no pumps or hydraulic fluid involved. Electric power steering cars are also less expensive than hydraulic ones. Since electric power steering uses 90% less energy than hydraulic steering, it helps engines last longer, reducing maintenance costs. BMWs, for example, use both electric and hydraulic steering systems. Electric power steering in a BMW provides precise control and reduces fuel consumption. It's considered superior to hydraulic power steering because it removes the layer of feedback between the driver and the road surface.
