Techniques for detecting supercharger belt slip |
摘要 |
A technique can include receiving, at a controller for a vehicle, the controller including one or more processors, a signal indicative of a pressure in an intake manifold of an engine of the vehicle. The vehicle can include a supercharger configured to supply pressurized air to the intake manifold. The supercharger can be driven by a crankshaft of the engine via a belt. The technique can include estimating, at the controller, a frequency of the signal to obtain an estimated frequency. The technique can include determining, at the controller, whether the belt is slipping based on a comparison between the estimated frequency and a predetermined frequency. The technique can also include outputting, at the controller, a notification when the belt is determined to be slipping. |

1. A method, comprising:
receiving, at a controller for a vehicle, the controller including one or more processors, a signal indicative of a pressure in an intake manifold of an engine of the vehicle, wherein the vehicle includes a supercharger configured to supply pressurized air to the intake manifold, and wherein the supercharger is driven by a crankshaft of the engine via a belt; estimating, at the controller, a frequency of the signal to obtain an estimated frequency; determining, at the controller, whether the belt is slipping based on a comparison between the estimated frequency and a predetermined frequency; and outputting, at the controller, a notification when the belt is determined to be slipping. |
