Abstract
An EVC include a coefficient estimation unit, a limit calculation unit, and a target-setting unit. The coefficient estimation unit estimates a maximum friction coefficient of a drive wheel with respect to a front road surface when a mobile body causes the drive wheel to rotate and travels on the road surface. The limit calculation unit calculates a torque upper limit for driving the drive wheel according to the estimated maximum friction coefficient. The target-setting unit sets a target torque to drive the drive wheel so as not to exceed the torque upper limit.
Claims7
A control device comprising:
- a coefficient estimation unit that estimates a maximum friction coefficient of a drive wheel with respect to a road surface when a mobile body causes the drive wheel to rotate and travels on the road surface;
- a limit calculation unit that calculates a torque upper limit for driving the drive wheel according to the estimated maximum friction coefficient;
- and
- a target-setting unit that sets a target torque to drive the drive wheel so as not to exceed the torque upper limit.
A non-transitory computer-readable storage medium storing a program thereon, the program comprising instructions, upon being executed by a control device, that cause the control device to perform a process, the process comprising:
- estimating a maximum friction coefficient of a drive wheel with respect to a road surface when a mobile body travels causes the drive wheel to rotate and travels on the road surface;
- calculating a torque upper limit for driving the drive wheel according to the estimated maximum friction coefficient;
- and
- setting a target torque that drives the drive wheel so as not to exceed the torque upper limit.
