  • Publication number: 20240141820
    Abstract: Method and systems for determining when to cancel coolant stop. An initial coolant temperature value is measured. The initial coolant temperature value is used to create Multiple Control Valve (MCV) opening thresholds. A first threshold is generated for MCV opening threshold for engine speed. A second threshold is generated for MCV opening for intake air mass flow. A comparison is made between the first threshold and the currently measured engine speed and/or a comparison is made between the second threshold and the currently measured intake air mass flow. The comparison(s) are then used to determine when to cancel coolant stop and open the MCV.

  • Publication number: 20240140529
    Abstract: A driving assistance device includes a sensor configured to detect a moving object ahead of a target vehicle and obstacles including a first obstacle and a second obstacle, and a control device. The control device is configured to determine whether the second obstacle is present. The second obstacle is located opposite to a traveling lane of the target vehicle with respect to the first obstacle in a lateral direction and forces the moving object to move in the lateral direction toward the traveling lane due to collaborative action with the first obstacle. The first obstacle hinders the moving object from moving in a longitudinal direction. The control device is configured to relax an execution condition of steering assistance for detouring around the moving object in a case where the second obstacle is present rather than in a case where the second obstacle is not present.

  • Publication number: 20240141847
    Abstract: When the element temperature of the air-fuel ratio sensor becomes equal to or higher than the activation temperature, the electronic control unit starts the detection of the air-fuel ratio based on the sensor output of the air-fuel ratio sensor and the air-fuel ratio feedback control based on the detection result. The electronic control unit calculates the air-fuel ratio detection value by setting the gain of the air-fuel ratio detection value with respect to the sensor output when the sensor output is a value indicating the air-fuel ratio richer than the stoichiometric air-fuel ratio to a value smaller than that after the elapse of the synchronization period from the start of the air-fuel ratio until the element temperature becomes equal to or higher than the predetermined desorption convergence temperature.
