Hyundai Mobis began to roll out a state-of-the-art braking and parking system of its own development on a full scale after completing its mass-production system.
On February 6, Hyundai Mobis announced that the company was ready for mass production of the Remote Smart Parking Assist (RSPA) and the next-generation integrated MOBIS electronic brake (iMEB) at Cheonan Factory in South Chungcheong Province and Jincheon Factory in North Chungcheong Province, respectively.
The RSPA is a technology through which a car parks itself using 12 ultrasonic sensors when a driver presses down a smart key button outside the car. This function can be used only if the driver checks the parking space in advance and is within a 4-meter radius of the car. Conversely, a parked vehicle can be moved out of the parking space via remote control without a driver in the car.
In addition, Hyundai Mobis is planning to develop more advanced automatic valet parking (AVP) technology by the end of this year. AVP is technology through which a car moves to a ground or underground parking lot on its own when the driver steps out of the car at the entrance to a mart or a restaurant. This high-level autonomous navigation system requires ultrasonic sensors, cameras, object recognition sensors, high-precision maps and communications with parking systems of buildings among others.
The iMEB is a component that charges the battery through power generation by the drive motor by putting a brake on eco-friendly cars such as hybrid vehicles (engines + electric motors). The iMEB is the core system for green cars which slashes energy loss 70% compared with general braking systems for internal combustion engines and can make a 40% improvement to hybrid vehicles’ fuel efficiency.
Hyundai Mobis claims that the iMEB is the most advanced regenerative braking system existing today. First, the company replaced the current hydraulic filling-type braking pressure supply part with an electric system powered by a motor and combined the braking pressure supply part and the braking control part that controls braking functions such as body posture control. The braking control part also combines Forward Collision-Avoidance Assist (FCA), the Advanced Smart Cruise Control (ASCC) System and an electronic parking brake (EPB) function.
As a consequence, its braking responsiveness is 13% higher than that of globally leading products but its weight and cost are cut 5% and 30%, respectively, compared to a hydraulic filling-type separation system, Hyundai Mobis explained.
