Chery selects Freescale for next-generation automotive engine control

ABR Staff Writer Published 15 March 2011

Chinese automotive manufacturer Chery Automobile has selected Freescale Semiconductor for the advanced microcontroller (MCU) technology, for the engine control unit (ECU) in its future vehicle models.

The company said that it selected Freescale's Qorivva 32-bit MPC563x MCU family for its high performance, reliability and scalability.

In April 2008, both the two companies have established a joint development lab in Wuhu, China, which is focused on the development of vehicle and battery management, powertrain, body and in-vehicle entertainment systems, as well as hybrid-electric vehicle/electric vehicle technology.

In 2009, Chery developed the Chery Engine Management System (CEMS) based on Freescale's S12XE 16-bit MCUs.

The Qorivva MCU family Chery selected for its latest ECU is built on 32-bit Power Architecture technology.

The new Chery vehicle models using the higher-performance Qorivva 32-bit MCUs are expected to reach full production in 2012.

The company is developing a higher level engine management system (EMS) covering the VVT / EGR / GDI and other advanced control technologies, which will make the EMS more complex and demand more powerful computing capacity from the MCU.

Chery assistant president and director of Engine Control Department Zhu Hang said they believe Freescale Qorivva MCUs are an excellent choice for their new engine control unit.

"Because of its advanced and complex control functions, we expect the MPC563x family to be the main chip used in future Chery engine control systems," Hang said.
