Integrating Chassis Components in the Wheel Arch

摘要

REE’s vehicle x-by-wire-linked corner control components give OEMs unprecedented design freedom to create any electric vehicle, from last- and mid-mile delivery vans to commercial autonomous shuttles, all on a completely flat one- box chassis. Each corner has its own ECU, plus there iss a separate ECU that controls the four corner ECUs. “We are the only one in the world with an ECU in each corner,” said REE CEO, Daniel Barel. REE’s biggest challenge was getting the control software right, especially the redundancy and required levels of safety. “Those were achievable through our own cognitive system, which is paramount to the overall performance. ” While some EV innovators are developing corner modules with in-wheel drive motors, REE’s drive motors are very close to the wheel but not inside the wheel. “So it is high RPM, low torque, which gives us a lot of efficiency,” said Barel. “And the motor is fully sprung,” for better handling. In August 2020, REE Automotive signed a memorandum of understanding with Mahindra to establish a strategic collaboration for the development of electric commercial?vehicles. REE expects to be on the road with a commercial implementations of its modular EV platform technology by 2022.
