Description

Base class for a track test rig driver system.

A driver system must be able to report the current values of the inputs (throttle and post displacements).

Member Function Documentation

◆ SetTimeDelay()

void chrono::vehicle::ChDriverTTR::SetTimeDelay ( double  delay)
inlineprotected

Set value of the time delay.

During this initial time period, no driver inputs are generated.

◆ Started()

bool chrono::vehicle::ChDriverTTR::Started ( ) const

Return false while driver inputs are ignored (while the rig is reaching the ride height configuration) and true otherwise.

In general, outputs from the test rig should only be collected while Started returns true.
