    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/bd2b548724224cd6b2ba8132ccd461eb~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728091640&amp;x-signature=vatt%2B1YRE%2FdSktsKJeK1kPn5ccs%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在又一次的测试中，<span style="color: black;">咱们</span>就能看到<strong style="color: blue;">新算法下发了最大到5m/s2的减速度</strong>，智能重卡成功刹车避让，接着继续自动前行。从突发<span style="color: black;">情况</span>由安全员接管，到<strong style="color: blue;">重卡自主辞让、实现零接管，智驾系统算法性能的<span style="color: black;">提高</span>显而易见。</strong></p>
