Aiming to address the issue of traction torque arbitration in hybrid transmission vehicles during rapid acceleration and deceleration, a comprehensive analysis is conducted on the impact of different conditions on cruise condition. This paper analyzes the criteria for activating cruise mode, as well as introduces the state machine for cruise control. The calculation of torque requirements for cruise control is then presented, along with the introduction of traction torque coordination modules to mitigate drivability issues during cruise condition. This is followed by optimized calibration and comparative real-world vehicle testing. The test results demonstrate that this calibration method effectively resolves the challenge of excessive drivability performance in acceleration and deceleration, with real-world testing showing actual vehicle speed can rapidly catch up to the set cruise speed, significantly enhancing drivability. The optimization process can increase the time it takes for the actual speed to reach the set speed by 14.2%, and reduce acceleration oscillation to within 4m/s2 by 20%.
