Problems solved by technology

Additionally, at higher vehicle speeds (VS), increased loads (eg, from incoming airflow) can be applied to the rain disk and cause the rain disk to degrade
Additionally, engine degradation may occur if the rain pan is not mounted to the vent of the cowl while the vehicle is in operation (for example, due to the vehicle operator removing the rain pan) and rain begins to fall

Embodiment Construction

[0011] The following description relates to systems and methods for controlling the speed of a vehicle based on whether a rain dish is coupled within the vehicle under the vehicle's ventilation hood. like Figure 1A As shown, the rain pan may be installed in the underhood area of ​​the vehicle below the vents of the ventilation hood. The rain pan can capture rain entering the vehicle via the hood and divert the rain away from the engine, thereby reducing engine degradation. However, the rain pan can also block a portion of the airflow entering the vents of the hood from reaching the engine. As a result, engine cooling may be reduced when the rain pan is installed in the vehicle. like Figure 1B As shown, the rain pan can be manually removed by the vehicle operator. Removing the rain pan can increase the area of ​​airflow that enters the hood and reaches the engine, thereby increasing cooling airflow to the engine. like figure 2 As shown in the exemplary method shown at ,...

Abstract

The present invention relates to a method and system for operating a vehicle having a hood and rain pan. Methods and systems are provided for controlling the speed of a vehicle based on whether a rain dish is coupled within the vehicle under a ventilation hood of the vehicle. In one example, a method includes maintaining a vehicle speed of the vehicle below a set vehicle speed threshold and alerting a vehicle operator of any The set vehicle speed threshold. In another example, the set vehicle speed threshold may be reduced due to the presence of rain.

Description

technical field [0001] The present invention generally relates to methods and systems for controlling a vehicle based on whether a rain tray is coupled within the vehicle under a vented hood of the vehicle. Background technique [0002] The vehicle includes a hood at the front end of the vehicle to protect the vehicle's engine and additional underhood components from external elements, such as rain. In some vehicles, the hood may include one or more vents (eg, in the form of louvers) on the top surface of the hood. These vents create a vented hood that allows airflow into and out of the hood. In one example, ventilation airflow from under the hood reduces the amount of lift on the vehicle, thereby increasing vehicle control (eg, stability). Additionally, the ventilation hood allows for increased airflow to engine components such as, for example, heat exchangers, thereby increasing engine cooling. However, the vents of the ventilation hood may also allow external elements,...
