Another source of friction was Tesla’s proprietary system that captured energy from when drivers decelerated, said Jeff Liker, a University of Michigan engineering professor who met with Toyota’s RAV4 EV engineering team last year.
“Toyota couldn’t share their actual code with Tesla, and Tesla couldn’t share their actual code with Toyota,” he said. “The way they explained it was like, ‘this is a black box.’ ”
Toyota’s team balked at the lack of a common car component called the parking pawl — the part of the transmission that backs up the parking brake.
Instead, Tesla proposed putting in an electronic parking brake after the company experienced difficulties with the pawl it used when developing the Roadster, one person said. Toyota’s engineers were impervious and the pawl was put into the RAV4 EV.
