AI Technical Summary
Technical Problem
Existing in-cylinder braking systems cannot dynamically adjust braking force according to actual operating conditions, which may lead to insufficient or excessive braking under complex slope conditions, affecting driving smoothness and fuel economy.
Method used
By monitoring the vehicle as it enters a downhill state, real-time vehicle speed and braking information are obtained, braking power is calculated, and the opening and position of the cylinder exhaust valve are adjusted to achieve in-cylinder braking, working in conjunction with the basic braking system.
Benefits of technology
It effectively stabilizes downhill speed, reduces driver intervention frequency, avoids overheating of the braking system, and improves driving safety and fuel economy.
