The invention relates to an engine oil dilution control in a hybrid vehicle. A vehicle includes an engine and a controller programmed to, responsive to an estimated oil dilution level of the engine exceeding a first threshold, issue commands such that regenerative braking is inhibited to increase a temperature of the engine, and responsive to the estimated oil dilution level falling below the first threshold, discontinue issuing the commands. 本公开涉及混合动力车辆中的发动机机油稀释控制。种车辆包括发动机和控制器，该控制器被配置为：响应于发动机的估计的机油稀释水平超过第阈值，发出命令，使得再生制动被禁止以提高发动机的温度，并且响应于估计的机油稀释水平降到第阈值以下，中止发出命令。
