Abstract

There is disclosed a method of operating a tipper vehicle, the tipper vehicle comprising a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body. The method comprises monitoring at least one of (i) a pressure parameter relating to the hydraulic pressure within the hydraulic cylinder and (ii) an angular positional parameter relating to the angular position of the tipper body; determining a maximum permissible vehicle speed based on at least one of the monitored (i) pressure parameter and (ii) angular positional parameter; and displaying the maximum permissible vehicle speed.

Claims

1. A method of operating a tipper vehicle, the tipper vehicle comprising a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed there between and actuatable to pivot the tipper body, the method comprising:

monitoring at least one of (i) a pressure parameter relating to the hydraulic pressure within the hydraulic cylinder and (ii) an angular positional parameter relating to the angular position of the tipper body;

determining a maximum permissible vehicle speed based on at least one of the monitored (i) pressure parameter and (ii) angular positional parameter; and

displaying the maximum permissible vehicle speed.

2. The method according to claim 1, comprising:

monitoring both the pressure parameter and the angular positional parameter, and

determining the maximum permissible vehicle speed based on at least the monitored pressure parameter and angular positional parameter, wherein the pressure parameter is generated by a pressure sensor which measures the hydraulic pressure within the hydraulic cylinder and wherein the pressure sensor is mounted to the hydraulic cylinder.

3. The method according to claim 1, wherein the angular positional parameter is generated by an inclination sensor, wherein the inclination sensor:

a) measures the inclination of the hydraulic cylinder, and is mounted to the hydraulic cylinder;

b) measures the inclination of the tipper body, and is mounted to the tipper body.

4. The method according to claim 1, wherein the angular positional parameter is generated by a rotary position sensor, wherein the rotary position sensor measures the angular position of:

a) the hydraulic cylinder about a pivot axis of the hydraulic cylinder;

or

b) the tipper body about the pivot axis of the hydraulic cylinder.

5. The method according to claim 1, further comprising receiving the vehicle speed from an engine controller of the vehicle.

6. The method according to claim 5, further comprising one or more of:

a) generating an alert if it is determined that the received vehicle speed is greater than the determined maximum permissible vehicle speed; and

b) lowering the tipper body towards the resting position if it is determined that the vehicle speed is greater than the maximum permissible vehicle speed.

7. A system for a tipper vehicle, the tipper vehicle comprising a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body, the system comprising:

a tipper body monitoring module arranged to monitor at least one of (i) a pressure parameter relating to the hydraulic pressure within the hydraulic cylinder and (ii) an angular positional parameter relating to the angular position of the tipper body;

a maximum permissible vehicle speed determining module arranged to determine the maximum permissible vehicle speed based on at least one of the monitored (i) pressure parameter and (ii) angular positional parameter; and

a display arranged to display the maximum permissible vehicle speed.

8. The system according to claim 7, wherein the tipper body monitoring module is arranged to monitor both the pressure parameter and the angular positional parameter, and wherein the maximum permissible vehicle speed determining module is arranged to determine the maximum permissible vehicle speed based on at least the monitored pressure parameter and angular positional parameter.

9. The system according to claim 7, further comprising a pressure sensor arranged to measure the hydraulic pressure within the hydraulic cylinder and arranged to generate the pressure parameter, further comprising an inclination sensor arranged to generate the angular positional parameter, and further wherein the inclination sensor is arranged to measure the inclination of the hydraulic cylinder or the tipper body.

10. The system according to claim 7, further comprising a rotary position sensor arranged to generate the angular positional parameter, wherein the rotary position sensor is arranged to measure the angular position of:

the hydraulic cylinder about a pivot axis of the hydraulic cylinder;

or

the tipper body about the pivot axis of the hydraulic cylinder.

11. The system according to claim 7, further comprising a vehicle speed monitoring module is arranged to monitor the vehicle speed, wherein the vehicle speed monitoring module is arranged to be connected to an engine controller of the vehicle such that it can receive the vehicle speed from the engine controller, and further comprising an alert generator arranged to generate an alert if it is determined that the vehicle speed is greater than the determined maximum permissible vehicle speed.

12. The system according to claim 11, further comprising a hydraulic cylinder control module arranged to actuate the hydraulic cylinder to lower the tipper body towards the resting position if it is determined that the vehicle speed is greater than the maximum permissible vehicle speed.

13. A tipper vehicle comprising

the system in accordance with claim 7.

14. The tipper vehicle according to claim 13, wherein:

a) a pressure sensor is mounted to the hydraulic cylinder; and

/or

b) an inclination sensor is mounted to one or more of the hydraulic cylinder or the tipper body.
