1. A method for improving the operational performance of a moving cement mixer vehicle having a rotating mixing drum, the method comprising the steps of:
- receiving input data indicative of a steering angle;
comparing the input data to a steering angle threshold value;
determining if the input data indicative of a steering angle of the vehicle exceeds the steering angle threshold value;
receiving input data indicative of at least one of a lateral acceleration and vehicle speed;
automatically adjusting at least one of a lateral acceleration and vehicle speed threshold value based on the input data indicative of the steering angle exceeding the steering angle threshold value;
comparing the input data indicative of at least one of the lateral acceleration and vehicle speed to at least one of the adjusted lateral acceleration and vehicle speed threshold value;
wherein one or more trigger events corresponds to the input data indicative of the at least one of the lateral acceleration and vehicle speed exceeding at least one of the adjusted threshold value for the lateral acceleration and vehicle speed input data; and
supplying a control signal for automatically stopping rotation of the mixing drum when the one or more trigger events are occurring.

Abstract
A system and method are provided for improving the operational performance of a moving cement mixer vehicle with a rotatable mixing drum by automatically stopping the rotation of the mixing drum at select moments. The system may include a sensor adapted to deliver a signal indicative of an operational parameter, such as steering angle of the vehicle, and a processing unit adapted to receive the signal from the sensor and deliver a control signal based on the signal for stopping rotation of the mixing drum.

9. A method for improving the operational performance of a moving cement mixer vehicle having a rotating mixing drum, the method comprising the steps of:
-
determining that at least one trigger event is occurring on the vehicle, wherein the at least one trigger event includes at least one of;
an anti-lock braking event, an intervention by an automatic traction control system, and intervention by an electronic stability control system; andreceiving input data indicative of a steering angle; receiving input data indicative of at least one of a lateral acceleration and vehicle speed; automatically adjusting at least one of a lateral acceleration and vehicle speed threshold value based on the input data indicative of the steering angle; comparing the input data indicative of the at least one of the lateral acceleration and vehicle speed to at least one of the adjusted lateral acceleration and vehicle speed threshold value; and supplying a control signal for automatically stopping rotation of the mixing drum if the at least one trigger event is occurring and the input data indicative of at least one of the lateral acceleration and vehicle speed exceeds at least one of the adjusted lateral acceleration and vehicle speed threshold value. - View Dependent Claims (10, 11, 12)
