Abstract
A tilt monitoring assembly (200) for a yard maintenance vehicle (10) may include processing circuitry (210) configured to receive speed information indicative of a current speed of the vehicle (500), receive orientation information indicative of a three dimensional orientation of the vehicle (510), receive weight information indicative of operator weight associated with a driver of the vehicle (530), determine a tilt status based on the speed information, the orientation information and the weight information (540), and provide an output associated with operation of the vehicle based on the tilt status (550).
Claims15
A tilt monitoring assembly for a yard maintenance vehicle, the assembly comprising processing circuitry configured to:
- receive speed information indicative of a current speed of the vehicle;
- receive orientation information indicative of a three dimensional orientation of the vehicle;
- receive weight information indicative of operator weight associated with a driver of the vehicle;
- determine a tilt status based on the speed information, the orientation information and the weight information;
- and
- provide an output associated with operation of the vehicle based on the tilt status,
- wherein the output comprises an alert or instruction to the driver associated with vehicle control based on the tilt status, or an automatically initiated control instruction associated with steering control, speed control or brake control based on the tilt status.
A tilt monitoring assembly for an articulated yard maintenance vehicle, the assembly comprising processing circuitry configured to:
- receive speed information indicative of a current speed of the vehicle;
- receive orientation information indicative of a three dimensional orientation of the vehicle;
- receive angle information indicative of an angular difference between headings of a first part of the vehicle at which front wheels are disposed and a second part of the vehicle at which rear wheels are disposed, the first and second parts of the vehicle being operably coupled via an articulated joint;
- determine a tilt status based on the speed information, the orientation information and the angle information;
- and
- provide an output associated with operation of the vehicle based on the tilt status,
- wherein the output comprises an alert or instruction to the driver associated with vehicle control based on the tilt status, or an automatically initiated control instruction associated with steering control, speed control or brake control based on the tilt status.
A riding yard maintenance vehicle comprising:
- an articulated frame comprising a first portion to which front wheels of the vehicle are attached and a second portion to which rear wheels of the vehicle are attachable;
- a steering assembly operably coupled to the front wheels or the rear wheels of the vehicle to provide steering inputs by an operator of the vehicle;
- and
- a tilt monitoring assembly comprising processing circuitry configured to:
- receive speed information indicative of a current speed of the vehicle;
- receive orientation information indicative of a three dimensional orientation of the vehicle;
- receive angle information indicative of an angular difference between the first and second portions of the vehicle;
- receive weight information indicative of a weight of the operator;
- determine a tilt status based on the speed information, the orientation information and the angle information;
- and
- provide an output associated with operation of the vehicle based on the tilt status,
- wherein the output comprises an alert or instruction to the driver associated with vehicle control based on the tilt status, or an automatically initiated control instruction associated with steering control, speed control or brake control based on the tilt status.
